This super fun set is in very good condition!
Hand made, and I believe it to be wool, but the cape is lined and not itchy, and I'd suggest a half slip under the skirt, although not terribly itchy, will stick to tights.

This will best fit a size small.

Waist laid flat 10 inches (shown on a 27 inch waist and perfectly comfortable, has excellent elastic)
Total length 21.5 inches

Cape total length 27 inches
