Peplum type style fitted top PLEASE READ SIZE

Very fitted with a square neck. Lots of stretch in this too. Wore for a few special occasions but in terrific shape. Arm pit to armpit without stretch is 15 inches. Length is 23. Probably a M but the rage was cut out. Ask any questions before please, I look over all the clothes for flaws and list what I find. I’m happy to bundle clothes for even more discount, BOGO. No trades, sorry. #4
