Crimping was cool — VERY cool — when we were in middle school. My sister Lucy really rocked it. Fifteen years later, crimping’s making a comeback. In the runway shows this spring, Chanel crimped their models’ hair; Michael Kors crimped and then twisted hair into buns; Alberta Ferretti did such a subtle crimp that the models looked like they had just a bit of frizz from an ocean breeze. Don’t you think it would be fun to pull out the dusty crimping iron and flashback to seventh grade? Just remember: Subtlety’s key.
