Not sized like the rest of my size large bottoms. Seems like a medium.
These swimsuit bottoms are nice, but run very small. I wear a women's small is just about everything, but I could barely get the small I ordered in these past my thighs. I think I would at least need a large, which is what I wear in junior's sizes, so my guess is that's what the sizes are based on. I would have loved to simply exchange these because the pattern is cute, but I couldn't get the matching top in a larger size to go with them, so I had to return them.
