I'm usually a L in LOF tops, but M fit better
"LOVE this colour. I love that this style is better for tanlines than some of the other bikini tops I own from LOF. It's supportive and my girls stayed in for the most part. The L had gaps on the outer sides of my boobs, and the band was a bit big, so I'm glad the medium fit, though my boob starts to sneak out from time to time. The straps dug a tiny bit into my shoulders, but not too bad. Overall love this top, reached for it the most on my summer vacay for the better tan lines. I'm a 34DD bra size btw."
