Vintage Wool Skirt Union Made

This is a vintage wool skirt. It has a union label but I see no other labels. I took the pictures this way but not sure which way it would have the zipper/ pleat. There is a 1/2 lining on (as pictured) the back. The front has a blind button and zipper on the top, a faux slit in the middle, and to finish the line a pleat. There are belt loops at the waist. There is a yellow string popping out at the belt line. There is some piling but not bad. It is about 28 inches long and 26 wide.
