Custo Barcelona cap sleeve top Size X Small-Small

Size and fabric content tags are missing. 15” pit-to-pit and the across the bottom hem. Shoulder to hem 22”. Waist 12.5”. Measurements taken lying flat un-stretched. Probably a size 1 (XS) but could be a 2 (S). I think it’s an XS because the arm holes are unusually tight on my upper arms. Velvet trim on arms and at neck. Beautiful colors. Discounted shipping!
