It's a cape AND it's a skirt. It was made in the 70s from the skirt on a 40s/50s velveteen dress. A black satin belt from an old kimono was threaded through the top to tie into a bow.
This has a LOT of versatility. It's a cape, shown, obviously. It's an overskirt to wear open in front over a mini skirt (shown with plaid skirt). or open in front with a crinoline (also shown). Wear as a skirt but you have to make sure it's closed in back....or not🤭. Last but not least, in the 50s, many savvy hostesses wore these over their slim slacks (also shown).
So do your thing!
There is one flaw. A repair fixed with Stitch Witchery, patched up. It's shown from the inside and outside.
