GET THE LOOK: Most leading ladies rely on flowing waves to turn heads. But when you're Posh, all you need is a pair of heels and a tan. As if to challenge her own sexiness, Victoria Beckham morphed her glam bob into a slick men's style reminiscent of Cary Grant. Whether she stows an Ace comb and a cigar in her evening clutch remains to be seen. But she's just as smokin' hot as ever.

GET THE LOOK: Everything's coming up roses for Jessica Biel, who sported a vivid rose pout at the BFI Film Festival in London. The darker your skintone, the more pigment you can wear. If you have light skin, try either a deep color in a sheer formula or a light shade in an opaque lipstick.

INSIDER TRICK: Pink protocol: Biel wanted to wear a loud mouth, even though she has a light complexion. To make it work, she echoed the color on her cheeks and kept her eyes simple and nude.

GET THE LOOK: Amy Adams is lightening up—not that she was ever uptight. She traded in her signature auburn locks for light caramel strands. "People say you should go darker with your caramel hair color in spring, but that doesn't mean go to dark brown," says celebrity hair colorist George Papanikolas of Joico. Instead, if you're looking for a change, ask your colorist for a bright, but warm tone.

INSIDER TRICK: Make a desposit! Counteract the effects of sunlight and color-fading on light hair by rinsing with color-depositing shampoo, advises Papanikolas. "To get the best results, use it only once a week or add some to your regular shampoo to dilute the pigments," Papanikolas adds.
