TREND: HEADBANDS

DO: Wear them with updos as an accent, says Gage, and go for "luxe fabrics like satin and velvet" (as seen on Sienna Miller and Sandra Bullock).

DON'T: Push them all the way to the middle of your hair – "that's a schoolgirl look," says Gage. "You want to place them 1 to 2-1/2 inches back from the hairline."
