11. Leith Clark
The young London-based stylist has two of fashion's It girls, Michelle Williams (up through the Oscars, at which time Elizabeth Stewart took over) and Keira Knightley (in addition to styling her for the red carpet, Clark also did Knightley's most recent ad for Chanel's Coco Mademoiselle fragrance).
12. Estee Stanley
Stanley glams up Jessica Biel (who most recently stepped out in Atelier Versace at the Vanity Fair party), and she's responsible for putting Glee's Lea Michele in all of her elegant Oscar de la Renta dresses. In addition to red-carpet styling, Stanley spends time doing editorial styling and interior design.
13. L'Wren Scott
She's a former model-turned-stylist-turned-full-time designer (Penelope Cruz and Amy Adams both wore her dresses to the Oscars), but she still makes the list for semi-secretly styling longtime client and friend Nicole Kidman, who donned Prada, Nina Ricci and L'Wren Scott this season. It's rumored that Scott also helps Sarah Jessica Parker.
14. Jessica Paster
Paster persuaded Annette Bening to trade in her black pantsuits for more glamorous styles this season including a beaded Tony Ward dress at the SAGs and Marchesa at the BAFTAs. She also keeps Emily Blunt looking chic.
15. Rob Zangardi & Mariel Haenn
The styling duo works with Jennifer Lopez, Rachel McAdams, Will Smith and Jada Pinkett Smith and Rihanna -- enough said.
