Step aside, pale pink: There's a new neutral nail hue for fall—putty. These mushroom-esque mixes of gray and beige are perfect for active lifestyles; the colors are easy to paint on and the errant post-workout chip won't be obvious. "Putty shades are fabulous on both hands and feet," says Essie Weingarten, President and CEO of Essie Cosmetics, Ltd. "They're universally flattering, so any skin tone can wear them, but they look best on shorter, well-manicured nails." Our putty polish picks: Deborah Lippmann Nail Color in Waking Up In Vegas ($16; below left), and Essie Nail Polish in Chinchilly ($8; below right). What new polish hue will you treat yourself to this fall?
