@QueenOfTheAndals Actually, I think American Tan may also be British. I don't remember a color with that name in any US brand of pantyhose back in the day when we wore them all the time. The color I wore was called "Barely There".
Pantyhose keep trying to make a comeback in the US, fueled in part by Duchess Kate's wearing them, but they have definitely not made it back in my (warm climate) neck of the woods.
