At time of purchase, the tag and label had been ripped off (see photo), but the closest I can tell, it's by Roxy. (This is just my best guess after a lot of internet searching.) It fits me perfectly, and I am a large size 14/small 16, which is why I've estimated the size to be XL. Please see measurements for details and fit info! It's a sexy swimsuit, but I ultimately wasn't comfortable with that much showing. Open to offers!
