With everyone from Madonna to Gwen Stefani copping her New Wave chic, it's no surprise that pop songstress Ashlee Simpson would follow suit. Harry herself has shrugged off the attention: "I want to be identifiable as a performer, but I'm not wild about fashion." 02 of 08 Stevie Nicks and Mary-Kate Olsen Michael Ochs/Getty; Richard Young/Startraks When Stevie Nicks called her look a "funky but expensive Gypsy thing," she may as well have been talking about Mary-Kate Olsen's luxe layers. Nicks has called her wardrobe a "little uniform" developed to ward off stage fright, but if Olsen is any indication, the so-called "little uniform" is here to stay. 03 of 08 Tina Turner and Beyonce Dave Hogan/Getty; Jamie McCarthy/WireImage " Tina Turner is someone that I admire, because she made her strength feminine and sexy," Beyonce Knowles told Cosmopolitan. Sexy indeed, with her tousled hair and short skirts. "I don't want to worry about clothes tripping me," Turner has said of her stage wardrobe. And she may not mind showing off her legendary legs in the process. 04 of 08 Pat Benatar and Sienna Miller Michael Ochs/Getty; Stephen Lovekin/WireImage Pat Benatar did the no-pants look decades before Sienna Miller thought to hit the town sans bottoms. "This came from a Halloween costume I wore," Benatar has said of her onstage leotard. "I was dressed as a character from this ridiculous B movie called Cat-Women of the Moon. This was ridiculous then; it's so ridiculous now." 05 of 08 Janis Joplin and Mischa Barton Alan Band/Keystone/Getty; Seth Browarnik/WireImage Janis Joplin embodied the bohemian sixties in her bell-bottoms, fringe and velvet...and today's style stars are paying attention. Free-spirited Sienna Miller has said of Joplin: "She covered herself in jewelry and was free in how she dressed. I love that." Mischa Barton also brings a Joplin-flavor to her wardrobe with fringed jackets, studded boots and a laidback approach. "For the most part, I put my own looks together," she told the Times of London. "I'm not a huge shopper." 06 of 08 Joan Jett and Hilary Duff Chuck Krall/Michael Ochs/Getty; WENN Both Joan Jett and Hilary Duff got their start as teens, Jett as a "jailbait rocker" in seventies punk band The Runaways, and Duff, well, on the Disney Channel. Still, how better for Duff to follow a trailblazer than in classic Converse? "I remember thinking, 'I hope one day people don't look at women like they're out of their minds when they want to pick up an instrument and play," Jett has said. "And I think we're getting a lot closer to that." 07 of 08 Marianne Faithfull and Kate Moss Keystone/Getty; WENN Musician and Rolling Stones muse Marianne Faithfull is happy to have Kate Moss follow her sartorial lead: "She's very complex, she's very like me, she's a Capricorn. I think she's great." In classic rockstar fashion, Faithfull and Moss both favor blunt bangs, shaggy furs and skintight leather. 08 of 08 Madonna Ron Galella/WireImage; Flynet Madonna has inspired everyone else, why should she not inspire herself? Jessica Alba has claimed to love her early look ("From wearing lace to being edgy, from being coy to speaking her mind, she's amazing all around-as an artist and as a woman") and Gwyneth Paltrow is fond of the present-day stylesetter: "She's a beautiful product of all her explorations and incarnations." As for Madonna, fashion has always been piece of the total package: "It's all part of my expression, my self-discovery."
