Forever 21 White Ribbed Half Zip Collar Crop Top

Forever 21 White Ribbed Half Zip Collar Crop Top size medium brand new with tags. This has some faint stains on the back as shown in the last photo, I have not attempted to wash since it's brand new but it looks like it would likely wash out but it's fairly unnoticeable regardless. Armpit to armpit measures approx 13.5 inches across, length approx 18 inches. 60% cotton, 40% viscose. This is a ribbed collar crop top with an o-ring half zip.
