Gloria Vanderbilt Beachwear Snap Front Swimsuit Cover

Gloria Vanderbilt beachwear Snap Front Swimsuit cover. White, short sleeve w/embroidered logo on a front chest pocket. There is a small spot on the front near the bottom. The pic of spot makes it look like the whole piece is yellowed. It is not. That is a reflection off of my tan couch. Otherwise, in good condition. No size tag, but by the measurements, would fit a L or XL? Pit to pit 21" Length 34" Measurements are lay flat and approximate. My home is smoke and pet free.
