Swim 365 Women's Plus Size Box-Pleat Cover Up

I bought two of these - one in my regular size and one a size bigger. I love the feel and ease of on/off. It also dries fairly fast. Three downsides: 1) they both stretched out width wise quickly; 2) when on, they tend to be “short” in the back (barely covering butt if you don't keep adjusting: and 3) lightweight so when it's windy, the skirt “inflates” (so be sure you have on something underneath).

Just what I wanted. Purchased previously from a different site; I've used this both as a beach cover-up and as a nightgown. The armholes are large, so if you are out in public, wear a bra or use it only as a bathing suit cover-up. Washes well and is cool.
