Proenza Schouler Vintage Semi-Sheer Cotton/Silk Blend Tunic (XS/Small)

I believe this is from the Spring 2012 collection. Made of cotton and silk, this blue and black tunic has short sleeves, slits on the sides, and buttons on the chest. The ends of the sleeves and the bottom is made of fringe material. There is a tiny spot, which is shown in photos, but overall great condition. Measurements shown in photos. Size: XS Tall
