Turn of the Century Union Suit

Found this wonderful light weight summer union suit in an old suit case we had in the warehouse. I'm not sure where we acquired it, I guess they were with a large group of things and I didn't notice it. The fabric is a wonderful crisp cotton with a super tiny houndstooth check. The checks are indigo blue. The construction is both hand stitching and machine. A very simple machine btw. The tailored worked buttonholes were overcast by hand. There are pleats on the outside of each leg.
