So this is such a CUTE swimsuit! It has that retro look that I love, but still really sexy. I'm 5'10, 36DD, 175lbs, 30" waist. Usually I wear a 10, but because of previous reviews I decided to order up to a size 12. It fits, but I think I could've gone with the 10 after all. Probably would've pulled me in more at the waist and maybe fit a bit tighter at the top...there's no way I could wear this in the pool without the halter strap attached. New favorite one piece!
