Totally sheer gauzy ivory pantyhose by Givenchy. The brief and toe sections are also sheer, and they have some slight shaping at the ankle and calf. The denier number is not marked but they are super sheer. Marked "Selected Gradings" - this is also stamped on the brief section of the tights. Not sure what it means. 100% nylon. In the original packaging. 1980s.
Unused, unworn old stock. I checked for flaws in case "selected gradings" means factory seconds, as they were sold in a discount store. I can find one small catch, as shown.
