Jason Wu short-sleeved black sweater

Black polo shirt style sweater with half zip and collar. Really cute with jeans or a skirt. The fabric is not like a bulky sweater but smooth, glossy & stretchy with vertical ribbed “stripes”. Branded silver zipper at front also has a hook & eye closure. In very good condition except for wear at the upper back (laundering failure on my part involving the zipper rubbing against the back fabric) - see last 2 photos. Size small, measures approx: 16” across chest 13” across hem 20.5” long 8” long sleeves 6” long zipper
