For the Van Cleef & Arpels store opening in New York last night, Blake Lively channeled Hollywood icons like Rita Hayworth and Veronica Lake. But the newest face (and hair!) of L'Oréal Paris modernized her classic waves with a vampy makeup look. We're taking notes to copy this style for our next red carpet event . . . or, you know, a fabulous holiday party.

Classic Curls: To get the sideswept waves, you can go really old-school and dust off your hot rollers. Use the medium-sized curlers to set dry hair. While you're waiting for the waves to sink in (about 20 minutes), steal Blake's makeup look below. No time to wait? You can get a similar but more relaxed curl using a one-inch iron. Wrap hair around the barrel so that curls fall away from the face, leaving a few inches out at the roots. Hold for 30 seconds. Finish hair with a holding spritz like Oribe Anti-Humidity Spray ($38).

Modern Makeup: While a typical cherry-red lipstick would complete the Old Hollywood theme, reach for something vampier for an updated take on the classic instead. Try Deborah Lippmann's Forsaken Set ($38), a dark wine lipstick and nail polish duet. To balance out the moody lip, it's best to go light on the eye makeup.

Blake wore champagne shadows to brighten up her blue eyes. We like Bobbi Brown Shimmer Wash in Beige ($22) because it can work for most skin tones. Apply the shadow to lids and inner corners. Then, wet an angled liner brush and swipe on the shimmering shadow along the lower lash line, too. You want to avoid overusing eyeliner and focus on the mascara for this look. Bring it full circle by dusting the same metallic shadow under brows and on cheekbones for a glow that rivals Blake's gala-ready style.
