While the bathing suit is super cute, it's snug. I got a size small. I normally fit a size small (and even sometimes x-small) with no problems, but not this time. A med. would have been way better. Sadly, they were out of med. in the color I wanted. I still fit in it, but it's kinda tight in the chest. I'm 35-26-36 and 5'4". If you're my size or slightly bigger, order a med. If you're smaller than me, this will likely fit you. If only the top part had an extra inch of give... I'll still wear it but it's disappointing. :(
