Once, I had a lady at the Prescriptives counter tell me that because of my pink and blue undertones, I should only wear blue-based lipsticks and cool-toned eye shadows. It wasn't until years later that I realized that she'd been totally wrong — I actually look much better in warm, bright oranges, yellows, and violets. Unfortunately, I'd already spent my teen years and a bit of my early 20s following her "expert" advice.

Almost every woman I've talked to has been given some truly crappy beauty advice, regardless of whether she immediately recognized it for what it was, or spent years laboring under a misapprehension. So it's time for a little catharsis: what's the worst beauty advice anyone ever gave you? And how did you find out they were wrong?
