Black short sleeve button up

Thrifted black short sleeve shirt! Great on its on or as a layering piece - got a lot of wear out of this but I've realized I have too many similar items in closet. I'm normally between S/M, fit of this is closer to M which is a nice oversized fit on me. Material: 100% Polyester Lay flat measurements: PTP: 22.5" Length from shoulder down: 20"
