Young Brunette Girl Wearing White Stockings In The Studio

Support
Stockings can be held up in one of three ways:
A garter belt (AmE), or suspender belt (BrE), is the most common way of holding up stockings. It is a piece of lingerie worn around the waist like a belt which has "suspenders" or "stays" that clip to the tops of the stockings to hold them in place.
"Stay-up" technology is the second most common means of support. The inside of the top of the stockings has a band (typically silicone) of elastic of highly tractive material that resists slipping down the thigh. This is considerably less reliable in the sense of assuring that the stockings do not fall down, and depends a great deal on the thickness of the thigh. Further, the elastic can be uncomfortably tight, leaving red marks and possibly aggravating varicose veins.
