hope that helps because those C-cups up there are definitely not C-cups. I have breasts about that size (maybe a bit bigger, it's hard to tell), and I'm a G-cup (in most brands at least, since this can differ from brand to brand)
You run into more problems binding to be flat-chested than binding for support because you are essentially attempting to squish yourself into your rib-cage. The breasts WILL be damaged if you bind often and tightly, binder or wrap.A large breasted woman trying to go completely flat will have breathing issues too and you can actually faint from it. And larger women will face more deformation than not-so-large chested ladies.
Binding for support tends to keep the breast shape because you're NOT trying to squish your breasts flat, and (if you know what you're doing) you're actually supporting your breasts in the right area. I would suggest non-elastic wraps for this. For me, I'm lazy so I just wear 2 different sports bras that support in different areas. I strongly suggest just investing in a really good sports-bra, unless you're cosplaying a sarashi.
I like how you did your tutorial, it is informative and I like seeing a range of sizes.
With that said, yeah, it is true some have to wrap an arm around their chest; I often have to, and that's only on the rare occasion that I run (and sports bras never help one little bit.)
I would like to point out that the measuring method you point out does not work very well for the larger sizes. When I do it, it often says that I'm 2-3 cups smaller than I actually will fit into.
As for back strain, it also makes some women slouch to try and hide them, or just from the weight, leading to bad posture if not careful.
...now, if only I were a little less cheap so I could bra shop somewhere other than the local Wal*Mart whose biggest in-store cup size is two too small for me
I'M SURE YOU LOVE HEARING ABOUT OTHER DEVIANT'S BOOBS. Seriously though, this set of tutorials is actually very helpful
Speaking professionally this is amazingly comprehensive and very VERY helpful. I have often had trouble with drawing a natural look to womens breasts shapes in my characters especially how they sit in relation to the shoulders when I draw the silhouetted curve for clothing and I must say, this has helped a great deal.
Thankyou very much
(i´ve only recently started networking here on dA and especially with tutorials i think it´s great to do so and help people widen their horizon even more comfortably, so i packed you there, even tho most are bound to find your tutorial even before mine. )
