Antique Women's Cream White Lace Slip Undergarments Dress

Antique handmade ivory colored women's lace slip (2 layers). This has been in my family for several generations (unknown age). Missing at least one snap in the back. 3 small stains (show in the pictures). Some discoloration due to age--I soaked it to remove some of the yellowing but it's still there to some degree.

17 3/4 across the waist. 17 1/2 across the chest.
