Black Ribbed Long Sleeve

This long sleeve is in GUC! It does have a little stretch mark in the knit material in the back of the top but it is not noticeable while wearing. Could definitely be worn off the shoulder or on depending on what you prefer. It's an XS but could fit up to a M. Please let me know if you have any questions! *Not Forever 21 just tagging it for exposure purposes. Photo of tag has brand on it :)
