While die-hard fans love her cheeky, Harajuku-inspired stage attire, Gwen Stefani's stunning red-carpet looks have long impressed forward-thinking trendsetters. To channel her tough-luxe attitude, belt a simple blue ball gown, then accessorize with noir pieces—from fringe heels and a rosette clutch to dark, vampy nails. Finish off the glamorous ensemble with Stefani's signature accent: bold red lipstick. After all, imitation is the sincerest form of flattery. —Susan Cernek
