Women's Swimwear Adrian Athletic Swimsuit Top

I am a 36C, so I bought a large. It fits just snug enough that it really supports while swim training.

Way too tight... Sad for such a cute suit....

I wear a size M or size 6 across the board. 5'5", 145 with an average to athletic build. I ordered a large at first but ended up with an XL that is none too big.
