This cute jacket is made of cotton with amazing embellishments. The tooling, edging and lace all mix together to make a terrific vintage looking cover up in almost any season. Could be paired with a camisole, tank top, short sleeves or even long sleeves. Ties in the front or could be left open. Gently used. Washes well but I would lay it flat to dry. Size is a guess since that part of the tag is gone. Probably 100% cotton or cotton blend.
