Wool, excellent quality. Suit jacket with knee-length skirt. Lined, with decorative pocket flaps (no actual pockets) and shoulder pads. Listed as size 6, but since it's vintage, it's smaller than a current-day 6. (Waist measurement on the skirt is about 26 inches. I'm about a 4, and both the jacket and the skirt fit me very well.) Please reach out with any questions on sizing-- I'm also open to offers.
