This is a rash guard skirt. The waist is approximately 72 cm. The length is about 50 cm. Please allow for slight errors. There is a small pocket on the back, more for decoration. You can wear it over a swimsuit. You can also wear it over rash guard leggings. You can also wear it by folding the waist as shown in the last photo. The ways to use it are endless. I forgot when I bought it. Please refrain from purchasing if you are concerned as it is a used item ♪
