With a deep side part and glossy curls, this down-do pretty much epitomizes old-Hollywood glamour. It’s a guaranteed winner for formal holiday affairs. To get the look: Start with a deep side part and dry hair. Then apply a generous helping of strong-hold mousse, and use the length of your fingers to pinch one-inch sections of hair perpendicularly down the length of your strands. Clip each pinch and spray with strong-hold hairspray to set the style.
