Description
EDIT: Although I have drawn an example with a breast simply protruding from the chest, this is not the case in reality. That example is just to illustrate the fact that the breasts are actually surprisingly far from collarbones.EDIT 2: Remember that this is not "the only and right" way of drawing breasts. This is how I draw them, and you may agree or disagree with me as you please
I'm back with part 2. It took pretty long to compile, and it's not comprehensive, but I believe it has some good points there and there. Note that these are my own observations and I'm not unbiased artist. I have my preferences that I follow to make appealing drawings.
In anime and manga, breasts aren't drawn too strictly according to the physics. The breasts tend to be placed higher, near the collarbones, because it makes them look young and perky. Drooping hardly ever takes place. In some hentai, breasts tend to look more realistic, but usually they are rather monstrous physics-defying lumps of perfect shapes. Also, girls without bras don't seem to be bothered about their breasts jiggling crazily around. In reality, what I have heard, breasts are quite a nuisance, with and without bras.
Anyway, I drew my own view of breast. Note, that these apply on breasts that are hanging free. Bras and clothing in general are factors that affect the shape of the breasts a lot. This is probably why people think breasts always look nearly perfect spheres, even without supportive piece of clothing. This is, of course, not the case. I hate anime figures with detachable clothing parts, as the breast don't fall like they should. Despite having six Revoltech Queen's Blade action figures with such feature, I bought them due to their excellent articulation, not for this obnoxious feature.
Here I wanted to emphasize the rib cage. As it's where the breasts are anchored, it's the most significant "object" that affect the shape, size and position of the breasts. Note that, the larger the breasts are, the more support they need to keep the shape. So a girl with small body can't offer as much supportive area for the breasts to anchor to like women with larger rib cage. Thus small girls tend to have smaller breasts and if they do have large breasts, they look quite different from those of bigger women.
Also pay extra attention to the understanding the 3D. Perspective is such a pain, but in order to draw anything, it's a must have skill. In order to draw the breasts, you need to understand where the beholder is looking at it, how the body is related to it etc.
Breasts also come in various shapes. However, I have only drawn shapes that I find attractive. That said, the breasts don't always follow the dynamics too strictly, especially the larger breasts. This is why I don't usually want to draw extra large breasts, as the dynamics in them are often too ridiculous
This is also why I drew "girly", "lady-like" and "motherly" body builds as a reference. It's quite natural that younger women have smaller breasts and body compared to older women due to growth. These are only archetypes though, what's drawn here are about women in general point of view.
And finally, as an apology, I'm sorry for illustrating under-aged looking girls in reference part. For the sake of practice, I wanted to try drawing different body builds. I want to make clear that I have no interests in kids. Also, I apologize for illustrating obaa-san. Just like with kids, I have no interests in very old women. Everything is for the sake of art and demonstrating the things the way they are. Don't expect to see more of these two extremes from me here on dA.
Hope you like!

Very interesting, shows your style in drawing breasts in a pretty informative way! Good job!

Amen, boobs are annoying. I mean, I sleep with bras just bc I'm too lazy ti put a new one on in the morning! They also are so f-ing sensitive. I have a cat that pinpoints your nipples and steps directly on them. Taking impact to the tits is like a foot to the testiculars.

Very nice addition to the world of breast drawing tutorials and guides. Isn't it weird that there are so many good breast tutorial/guides out there and yet still so many poorly drawn breasts?? Artistic license aside, I mean. You can usual tell when an artists knows damn well how to draw realistic breasts and chooses not to as a stylistic choice. It's a matter of practice and education I suppose.
On that note, I'd just like to add that there do exist girls with small frames and therefore small rib cages but large breasts and if drawing this phenomena it's important to consider the ramifications of that body type. In my case I come from a family full of large breasted women and was born with severe medical issues that have left me with a very small frame with little fat left on my body. Because the breasts and hips are one of the lasts places to lose fat on the body I still retain my family's typically large breasts. This causes additional, very uncomfortable and often painful medical problems such as spinal issues, lower back pain, and terrible muscle knots all throughout the shoulders and neck. If you are designing a character with a very small frame and large breasts and want to give the character realistic depth it helps to think about such things and consider whether or not to use them to flesh out your character's background.
A family friend of mine was born with a disorder that caused her breasts to grow to a tremendous size--far beyond the "average" range--despite her very, very petite 4'9" frame and she ended up choosing breast reduction surgery in order to avoid life threatening complications. Seriously it's not fun to have big breasts on a small frame. Think of your characters people, have mercy!! -____-' Anyways, good job on the tutorial, very instructive and easy to follow.

Yeah, I'm crying bloody tears every time I see nude characters in my deviantWATCH. And it seems people are quite eager to upload that kind of stuff, so it happens rather often.
True, girls with small rib cage and large breasts do exists. It's quite a shame that larger breasts cause so much complications 
In my style, I usually draw pear-like torso, which renders the rib cage rather small. It's really hard to fit large breasts in thin frame, so I usually avoid doing that. Besides, the body proportions look more appealing with reasonably sized breasts
Men would probably get boner just from thinking breasts expansion beyond imagination, but for her, it must have been really uncomfortable. Hopefully she is content with her decision now.

Yes, me too, and nude or close to nude art is so popular that half my inbox seems to be filled with anatomy perfectly designed to make me flinch, haha. Men see a picture of a guy being knees in the crotch and instinctively cross their legs. Women see a picture of a girl with a ridiculously tiny rib cage and huge chest and instinctively rub their lower back with a wince.
At least there are artists like you putting out tutorials designed to make people think about the realities of anatomy. I think it's a common mistake for even experienced artists to draw without considering anatomy. Or people use the excuse of "it's just my style" when they completely ignore anatomy.
The lovely thing about art though, is that an artist is never really 'wrong'. I don't think you ever stop learning as an artist, even the so-called 'masters' are still learning and growing because reality is so vast it's impossible to master.
👍: 0 ⏩: 1
Human body has always been the most interesting subject of study among artists, but I assume that most of the nude art here is more or less for personal satisfaction rather than pure intended study for mastering the beauty of human body
Although it's true that an artist is never really wrong, there are better and worse solutions for everything. By following certain rules it's possible to aim for the better solutions, and if the artist is gonna break those rules for even better results, she needs to know the rules she's breaking before doing so
👍: 0 ⏩: 1
Yeah, personally I know that I have a very long way to go before I can really establish my own style--although, of course, an artist is never really "done" learning art. But I feel that if I've learned anything over the years, it's that all of the great artists, no matter their stylistic difference, first worked by replicating and understanding reality and then played with leaving out some details and exaggerating others to create their own styles. Right now I'm definitely still at the "learning reality" part of that equation.
In the end it's wonderful that we live in a time where artists of every level, style, and culture can share their work so that we can all learn from one another. Tutorials like these and lots of the others on this site are gold mines since they are essentially one artist offering up what they've learned so that other artists might be able to benefit from it.

While your smaller breasts are indeed more accurate I can't help but feel some seem 'pasted' on. Maybe this is because you draw almost the whole contour of the breast. Which is not nessecairily needed while laying down. The mass of a breast flattens, the boobs droop from the chest but at the same time they are flattened against the chest by gravity and the skin holding them in place. Even the smaller breasts seem to have this kind of 'space' under them. Like the skin continues under the breast. I think this is because you give something a line that could be implied with just shade (like we don't usually draw the nosebridge). They aren't that 'flexible' and again it gives this illusion of liquid instead of mass (note how the fingers sink in the breast when she grabs them in the biggest example- there is some serious squeezing force needed to achieve this and I can assure you for natural breasts that would not go without pain and fake breasts tend to be too 'plastic' to do this). The fingers sinking in the breast is however possible if the whole breast is fitted in the hand (the mass isn't 'split up' but squeezed in a whole).
Breasts have got this really weird brain-looking tissue: [link] in case you didn't know!
I think that's maybe the problem, the lines that are drawn 'under' and 'inside' the breast at all times (which gives a wrong illusion)-this could of course be partly because it's a tutorial and you want to illustrate it as clearly as possible. But yeah, as you said you haven't done 'empiric research' before so some of these mistakes are understandable. I can easily complain because I'm a woman and have breasts myself. Either way I find watching amatuer porn with real people helps a lot understanding them a bit better, especially all the different shapes and sizes in movement!

In reality there are no lines, so defining certain forms with just outlines is somewhat tricky at times. But anyway, I believe I get what you are saying. Basically, I'm drawing either a line that shouldn't be there or it's too heavy (like you mentioned about the nose bridge). Too bad I'm quite big fan of bulky lines.
But then again, this is made in comic style, where some exaggerating and "cheating" is quite common (just like in art in general), so to say. And for that I have been used manga as my reference, more than real life (I guess I could do some more research there). Although I aim in some sort of realism, I believe I'm not even trying to make them look really accurate in relation to their real life counterparts. At least I'm trying to avoid making them spheres
I appreciate your honest opinions. You didn't let the artwork fool your eyes

Maybe the title is a bit misleading then, seeing as just plainly stating 'THE dynamics of breasts" is a bit absolute. Because I understand artistic preferences and whatnot but I personally find that the beauty lies in dramatising without making it look 'weird'. Rest of the body continues to be correct and in proportion and it just gives me an odd vibe. Of course the breasts are sexified and more objectified in this kind of art- Anyways I'm not bashing, just know that studying real body parts can always come as a revelation!

Will you do a part 3? With how clothing affects them?
👍: 0 ⏩: 1
I thought doing that, but I should get going with other works now. Besides, I don't think I'm good enough to make a demonstration about the clothing yet. For example, I haven't drawn bras very often, so I don't feel like making a demo about something I don't know very well.
I'll need to do some more studying first

Very understandable guide, I love it. Especially love how you crack down on the breast dimensions using curves, grids, line variations, and applying real world physics.
Thanks a bunch Nsio
👍: 0 ⏩: 0
This is a really good guide, but there is one thing that you should note.
Breasts aren't just protrusions from the chest. They actually kind of start under the arm pits, wrap around the ribs/chest area and then form the mass everyone usually thinks of when thinking of breasts.
👍: 0 ⏩: 1
Yes, I know it's not quite like that xD and I should have mentioned this. But I didn't draw demonstration about the matter, as I'm not quite sure how exactly the armpit area goes. Although there are some drawings that could serve the purpose.. oh well, I though that protruding thing would work as a nice simplification for understanding why the breasts are located surprisingly low on the chest
However, that laying down thing was good to know. I guess I should have drawn the breasts flatter in those two demos. Though, it also has a thing to do with my own taste and most importantly the fact that I don't have breasts to observe on my own xD.
Thanks for sharing this, it was really helpful!

perfecto, this is just what i needed, an instruction drawing about how to draw breasts. Thanks for this XD

This is a shot in the park.. But could you demonstrate the different cup sizes so people know what size their character would be? Like.. I'm a girl and even I still don't really understand the differences between the As and A-36, the Bs, Cs, Ds and DDs, etc.
👍: 0 ⏩: 1
As I'm a guy, I have even less understanding about the cup sizes! x'D. For me there are either flat, small, average or large breasts.
I guess the cup sizes vary between countries. What I do know is that the difference between chest girth on top of the breasts and chest girth under the breasts determine the cup size. So basically, if two characters had the same breast size but different chest girth, their cup sizes would be different.
This is probably because the supportive breasts tissue depends on the size of the rib cage. So in the above example, the girl with smaller rib cage would have rounder breasts, while the other has her breasts spread in larger area. Thus, the part we see of the breasts looks different in size in relation to the body of the bearer.
This is all about my own thinking, so I can't say if this is the case really

My thoughts are parallel with The obaa-san did catch me by surprise, but knowing about all breast types is essential.

ok things were going well until I saw the granny, she made my eyes twitch :L
but then again, you have to know how to draw females of every age, shape and form

Just observe a lot. I always read manga with care, looking how the mangaka has made everything. K-on, for example, has very cute hands and legs, so it' a good anime/manga to use as a reference 
Ja miulle voi kyllä puhua suomeakin sitten

Tarpeeksi usein ku vaa piirrät niin kyllä se alkaa tulemaan! Mie oon piirtäny heti puoleen kymmenisen vuotta, mutta vasta 4 vuotta sitten aloin oikeasti älyämään mistään mitään. Siitä lähtien on sitte koko ajan vaan kehittyny aika nopeasti.
Se on aika paljon vaa näkemisestä kiinni. Aivot kun jättää tosi paljon prosessoimatta, kun vähemmälläkin selviää. Taiteilijan pitää sitten oikein opetella näkemään asiat niinko ne todella on :'D

An true artist can look anything with pure innocence. xD
Thanks! I don't know if I'm gonna draw many tutorials, but I'll think about it. My scrap book is full of many demonstrations I have done to help my friends, so check it out
This [link] is probably closest to your interests. It's only one example, but that's how I usually construct my characters. I haven't done any comprehensive tutorials about the matter though.
👍: 0 ⏩: 1
Haha, I'm trying ^^
Well, you're really good at them so that would be amazing!
I will surely take a look!
Oh let's see ^^
Oh that's really helpful actually
Do you always sketch that whole thing?
Must take some time >u<
👍: 0 ⏩: 1
Heh, thanks. My friends find that my demonstrations are easy to understand, so maybe I should more of them.
I never sketch it in such detail, but I use a lot time in sketching. It's the most important phase, because the more carefully made sketch, the less mistakes in final piece. Also, mistakes in sketch are usually easier and faster to fix.
With sketching, I visualize the 3D shapes, so that I understand how to add clothing, shading etc. So that's why I usually draw some contours on the shapes
👍: 0 ⏩: 1
Yeah indeed! ^^
ahh, I see!
That's so true!
That's a good tip!
Do you have any tips on folds and perspective?
I really don't know how to do perspective >-<
👍: 0 ⏩: 1
Well, about drapes, you just need to know that the folds are formed in areas where the piece of clothing is loose, or it's manipulated with external force (gravity, stretching, wind blowing. The body under the clothing determines where the clothing is tight or loose, manipulated or free.
So if you lift your arm, the shirt around your shoulder gets loose and draping will occur. Around armpit, on the other hand, the shirt is stretched, thus deforming the surface and forming draping there.
To understand perspective, you just need to see the space you are in. Perspective is basically all about objects in space and their location in relation to each other (like my demonstration/exercise here [link] ). There are many tutorials how to construct perspective with horizon,vanishing points and guidelines. I recommend searching for those, there are plenty even in dA.
A good exercise for learning to see the world around you is to sit in front of a table and bring your eyes close to it's side. Now look around you WITHOUT moving your eyes. You will see that the perfectly square table is anything but square
It seems I wrote almost an essay already haha.
👍: 0 ⏩: 1
Ah I see!
I totally understand with the folds..
But now with the perspective.
I get what you're saying, but, when I draw a character, I can't help but draw them like
I'm rigt it front of them..
When I try to draw them from more below, it just seems out of propotions..
Also, when I try to draw, for example, a leg closer, it just looks really big >-<
I just don't seem to understand how to do that..

Wonderful reference on top of gorgeous eye-candy!
If I ever somehow manage to become an artist who can do a woman's body justice, it will be in part thanks to you.
If I ever become a pervert totally obsessed with boobs (more likely), it will be thanks to you too.
