Size S - I’d say it fits true to size as the straps are adjustable and it’s super stretchy! Only worn a handful of times — I just don’t wear it enough so I’m selling! There is a small dot on the upper left of the tank (see photo for reference) but it’s honestly barely noticeable! Please note the first photo is to show what it looks like on (Photo is not mine!) Let me know if you have any questions! *Also selling in white if you’re interested!*
