Yesterday, a friend pointed out her new mascara. She was wearing Benefit Bad Gal Blue, a violet-blue hue that's said to brighten the appearance of eyes. I haven't had much confidence with it—I'm worried that blue mascara will make me look like Whitney Houston circa "How Will I Know?", which is not my prerogative—but the whites of my friend's eyes did look bright. (Then again, they usually do.)

Well, it turns out the blue trend is going over very well: More than 130,000 units of Bad Gal Blue were sold during the first two weeks. If you're interested in hopping on the blue bandwagon, just pull out some Miles Davis (Kind of Blue, natch) and check out my guide to blue lip glosses. (And now, I'm going to go nibble on some blueberries.)
