let me start by saying I usually wear small clothes, but I am a DD and have a bigger booty so I usually get M in swim. this thing was massive and I can’t return it or exchange for smaller size. the bottoms are laughable, they look like a combo of granny panties and a diaper on me - they’re HUGE. the top is huge too and I NEVER have that problem, typically the opposite given my larger chest. girl just run. FN sizing has been so whack lately
