These lace thigh bands are 90% Nylon, 10% Spandex, making them pretty stretchy. They can be worn under dresses and skirts. I've heard they can be used as a fashion accessory with shorts, but I'm a bit old for that. I imagine it would be like a lace trim under shorter shorts?
Bandalettes are the only band I can find that has two bands of non slip silicone to keep the product in place. There has been no rolling or bunching as I wear them, and that's fantastic. You don't want to be pulling at them as you try to go about your day.
