Susan Powter is in full riot-grrrl mode

"Stop the insanity!" Workout guru and TV personality Susan Powter wears a faux-fur vest, bangle bracelets, nose ring, black fingernails and pink-tinted platinum-blonde hair in semi-dreadlocks at the opening reception for the art show "Rosie O'Donnell Presents Solace: An Exhibition of Paintings." This was at The Gallery at New World Stages in New York City on October 9, 2007.

Per Wikipedia, Powter's "platinum-white close cropped haircut, aggressive speaking manner, and habit of being barefoot while speaking in public became elements of her celebrity" during her heyday in the 1990s.
