Leave it to the always immaculate Olivia Palermo to give us hope for second-day hair on the impending holiday party circuit. The style star rocked slicked-back locks with a metallic fabric headband at last night’s Valentino event, a polished style that doesn’t require freshly shampooed tresses. Recreate her glamorous ‘do by parting hair in the middle and fastening into a low, sleek bun, taming any flyaways with a comb and glossing spray. Wrap a headband or metallic fabric of your choice around the head, fastening with pins on the underside of the bun. Finish with a sharp lick of eyeliner, rosy lipstick and sparkly stud earrings and voilà—you’re ready for a festive night on the town.
