Shaping waist slip (Shipley, BD18)

Waist slip from Avon many years ago, I have never tried this on, the size is 16-18, when I bought it I put it away in a drawer, .... and found it a few weeks ago ! I would say it looks more a size 14, I always thought Avon items were a very small fit. The first pic shows how it looks, the second shows the briefs that are attached the third is showing the clingy rubber edge to keep it in place, I have washed it just to freshen it up. Please let me know if you are interested. Guaranteed never worn.
