I am 120lbs, 5'0'' feet tall, and wear a 34 B cup size. I have never bought something that had such a low back because I've always been self-conscious about showing rolls, but oh my lord am I so pleased with this thing. The suit cuts off right at my tailbone in a soft "V" sort of shape, very slimming on my broad back. The fabric feels like a stretchy tank top, and it hugs my curves just right! I don't see an issue with it being see-through but there isn't any padding in the bust, so if you're someone who feels uncomfortable with only thin material covering your breast I suggest pasties, or even band-aids might do the trick. I'm not nervous about my breasts falling out, they feel held in place, though I can't speak for bustier ladies. Also it lifts your butt perfectly, without giving you a wedgie or a camel toe, and makes it look AMAZING. Great price for an even better product, it also shipped from California and arrived in 5 days right on time. Could not be happier with this, except that I wish it was also a bathing suit, because I would feel so confident stepping out on the beach and going swimming in this. You must buy it!!!!!!!
