Spice things up this season with some lemon zest. Not the teeny-weeny yellow beachwear for the sun and surf, this twist of citrus is intended for the spotlight. Flattering on nearly every skin tone, especially when spring's rays or the latest glow-in-a-bottle have added a hint of color, saffron shades brighten the complexion. Fair-faced Katie Holmes goes mellow yellow in complementing separates with metallic detail, while olive-complected Nicole Richie skips the butter in favor of sweet and creamy banana bow-tied silk. For something really refreshing, mix in bold accessories à la Paris Hilton's white pumps and clutch or Chloë Sevigny's pom-pom ankle-strap heels. Then watch as others eat their hearts out. —Wendy Manwarren
