The All Buttoned Up Swim Cover-Up features a classic fit that goes with so many swimsuit colors and styles. The front buttons can be fastened or left open and the sleeves are full length with traditional button closures (but can also be rolled up and securely held in place with a fabric loop above the elbow). The fabric is semi-sheer/breathable. It's also full coverage - hitting around the upper-mid thigh with a flattering side slit. This cover up is practically brand new. It has only been worn once or twice.
