Other forms: scrunchies
A scrunchie is a fabric-covered elastic for tying hair. Wear a scrunchie, a velvet scrunchie, a scrunchie on the wrist.
The fabric is the whole point, since it grips without the sharp pull of a bare band and leaves no crease. It was a 1980s invention, mocked for two decades and then back everywhere, which is how fashion works.
