LONG-SLEEVES RASH GUARD. Size: XS ( marked Size M)

A never worn, no tags, long-sleeved rash guard with a 1/4 zip top, mock neck, and chest modesty inserts. Cute bottoms with strings. The main color is black, with a tropical floral contrasting fabric. The reason I am selling this is because it is labeled a size M, but is, at most, a size XS. Please look carefully at the measurements.
