Chicos, black long sleeve crêpe tunic shirt size 1 (about a 12-14)

I’m not sure I ever wore this one, but it is not tagged. About 22 inches across the front from armpit to armpit. About 33 inches long. The sleeves are tabbed so that they can be rolled up. The back has an inverted pleat so that this is loose. And the material looks like crêpe.
