Vintage (c. 1959) Sliperfection Slip in Snow White Size 40/M

Vintage (c. 1959) Sliperfection Slip in Snow White Size 40/M A little piece of fashion history. I'm 98% sure that this is the exact slip from this 1959 ad in Women's Wear Daily. Even if it's not, Sliperfection went out of business in the late 1960s, so it's at least that old. In excellent vintage condition. The fabric has held up remarkably well over the past 64(!) years. There's one spot where the mesh came away from the lace that I mended with fabric glue in the mid-2000s. It's a 1959 size 40, roughly a contemporary medium. Pit to Pit: 20.5" Length: 40" 100% nylon tricot exclusive of decorations.
