I bought this top last summer when I was first introduced to Jolyn. I’ve worn it a few times swimming but always line dried. Jolyn runs a little small, which is why I’m selling this swim top. But this top will for sure stay put when swimming and jumping into the water! From the site: The Krizia top features our classic Triangle shape with unique fixed-back detail.
