Do not want. All I can think of is Elaine Benes and her fizzy poof pulled back from her face with a sad little clip. They never held my hair well, even at it's curliest, but they always managed to rip out a chunk in the hinge.
I can imagine a black or tortoiseshell clip working well accenting a French twist, but as a ponytail replacement? And the more elaborate barrettes, like these Cuteberry barrettes available at yesstyle.com, are way too twee to get near my baby face.
Are you excited about the resurgence of the barrettes or will you keep the hinges off your head?
