After seasons of “greige” on nails and lids, true cool gray is back. Dior is leading the trend with Smoky Grey eyeliner pencil (a ladylike alternative to black), Gris Montaigne polish (a dark slate), and—believe it or not—a lip shine. Ultra-Gloss in Trianon Silver is slightly intimidating in the tube, but rest assured it leaves lips subtly frosty, not cadaverous (at Sephora; $28, $21, and $26.50, respectively).
