Bundle of two vintage slips

Two vintage slips, one black and one peach-pink. I would guess that they are both from the 1960's. The black one has a tag that says 36 and that it's all nylon. It has a cool ruffle of sheer pleated material at the hem. It's in good condition, except that someone cut some of the trim off at the top of the back. But honestly, I've had this for years and worn it and never noticed that until I was inspecting it to list it. The pink slip has no tags, but is fairly large in the bust.
