Oh, the classic problem of big-breasted girls with small waists and rib cages. To be totally honest, you're probably wearing the wrong size anyway. I used to think I was a 34DD, but after being sized at a real store (not Victoria's Secret), I found out that I was a 28G. So, just a little side tip to maybe make your way over to a specialty store and get properly sized. But, the best way to buy a bathing suit top for breasts your size is to buy a bathing suit top that is sized like a bra, not S, M, L. (They're actually having their semi-annual sale right now.) Search "bathing suit bra size" on an online search engine for even more options.
how about a bikini that's similar to a bra
specail order it.. or buyseprates because normally the bust size they estimate on pantie size how should it fit on a woman of that particular shape the boobs matches the bodies frame lets say if someone were to get a boob job if that size they want isnt what there body frame can handle then there gonna have back problems and everything that comes with it
