“I was surprised that the medium was too big for me (top), I am a 34D in bra size, I am 5'5' and 135lbs. I haven't worn a size small swim suit top since high school! But the small was a better fit for me for my tankini. Beware they make you pay for shipping on a return and if you rebuy the size you want, they'll charge you shipping again, that was annoying but worth it since I love this top so much.”
“I am 5 foot tall, 122 #, athletic build, 34 B. I ordered a medium. I'm in fairly good shape, but 54, so the 'quality ' isn't that of 25 :(. So I prefer the tankini style for coverage, but I can roll it up if I'm feeling confident, or laying out. I'm not too big on top, so the push up model is helpful. Although, if you are considering the inserts to help yourself along, I think this is the only style that does NOT have the pockets to slide inserts into. (push up and inserts, cant have it all - lol).”
