Try it at home: Blow-dry your hair to get a smooth, satiny foundation. (For those with thick, frizz-prone manes, day-old strands will work better.) Next, add your waves with
GHD's Curve Soft Curl Iron ($245). Start at your cheekbones and stop two inches from the bottom so that ends remain slightly straighter. Finish by spritzing a texturizing formula "for a bit of fullness so that nothing appears stringy," advises Abergel. We like
Aloxxi Texturizing Spray ($20). Wear the style long and loose, or pull everything off your face with a metallic accessory for a Valentino-esque half-up 'do.
