Ugh swimsuit shopping is seriously the WORST. Like I'm not even weirdly shaped or anything - 5'7​,​ 140​,​ pretty normal body - but figuring out sizing has been a nightmare. BUT this one actually worked!! Got it in S classic and omg I'm so happy with it. The back is super cute and makes my butt look good which doesn't always happen. Only thing is there's no padding​/​cups so if you're weird about that stuff like me just fyi. I'm kind of a prude about these things so I noticed right away but it's not like a huge deal. Anyway I love this suit and will probably order another color because finding one that works is like finding a unicorn 😅
