6. Cristina Ehrlich
Ehrlich's longtime clients Penelope Cruz (winning look: a sizzling L'Wren Scott dress that showed off the new mom's curves at the Oscars) and The Fighter nominee Amy Adams (winning looks: Herve Leroux at the SAGs, Elie Saab at the BAFTAs and Marchesa at the Golden Globes) are both consistently chic. Julianne Hough, Kyra Sedgwick, Ashley Green and Julianna Margulies are also loyal clients.
7. Deborah Waknin
Halle Berry trusts Waknin, who has also done costume design for television, to pull together the most glamorous, sexy red-carpet styles, including her embellished Marchesa gown with Neil Lane jewels at this year's Oscars. Sandra Bullock also attributes her memorable looks from last year's Blind Side Oscar campaign to the veteran stylist.
8. Elizabeth Stewart
Stewart styled newcomer nominee Jennifer Lawrence for all of this year's awards-season events; she also worked with Michelle Williams on her Oscar gown. She also outfits Cate Blanchett -- the only fashion risk-taker at this year's Oscars in Givenchy Couture. Amanda Seyfried, Kristin Davis and Viola Davis are clients too. Pre-styling, Stewart had jobs at The New York Times Magazine and W.
9. Leslie Fremar
Fremar works with some of the fashion crowd's favorites including Reese Witherspoon, Julianne Moore (winning looks: Tom Ford at the BAFTAs and Lanvin at the Globes) and Charlize Theron. She got her start in the business as an assistant at Vogue and then as the celebrity dresser for Prada -- she's even rumored to be the inspiration for the catty co-assistant character Emily (Emily Blunt) in The Devil Wears Prada.
10. Jeanne Yang
Katie Holmes' personal stylist (they launched the clothing line Holmes & Yang together, which sells at Barneys and Los Angeles' Maxfield) also keeps Tom Cruise, Melissa Leo and Christian Bale well-dressed.
