CHARLIZE THERON: BEST
The best actress nominee (for North Country) mixes dainty and sexy in a lacy confection by John Galliano for Dior.
EVA LONGORIA: BEST
Desperate Housewife and best-actress nominee Longoria upstages the red carpet in a vibrant crimson gown by Bob Mackie.
SANDRA OH: BEST
She earned a Globe for her supporting role in Grey's Anatomy, but Oh's diaphanous, petal-pink gown was already a winner.
KEIRA KNIGHTLEY: BEST
Knightley, up for best actress for Pride & Prejudice, looks regal in a sleek column by Valentino and vintage Cartier earrings.
ANNE HATHAWAY: BEST
The Brokeback Mountain actress gets back to her Princess roots in shimmering navy Marc Jacobs.
FELICITY HUFFMAN: BEST
Huffman, nominated for playing both a woman (in Desperate Housewives) and a man (in Transamerica, for which she won best actress), is 100 percent feminine in empire-waisted Marchesa.
NATALIE PORTMAN: BEST
With her V for Vendetta buzz cut grown into a cute pixie do, Portman channels Audrey Hepburn in vintage Chanel.
TERI HATCHER: BEST
Hatcher, a best actress nominee for her klutzy Housewife Susan Mayer, is the picture of poise in glittering Versace.
KATE BECKINSALE: BEST
She plays a vampire in Underworld: Evolution, but Beckinsale looks entirely angelic in delicate, snow-white lace Christian Dior.
REESE WITHERSPOON: BEST
Witherspoon, who took a best actress trophy for Walk the Line, sticks with her winning formula: full-skirted and flirty (in Chanel).
SARAH JESSICA PARKER: BEST
The best actress nominee (for The Family Stone) pairs an elegant choker with a floor-sweeping Rochas gown.
MARIA BELLO: BEST
The best actress nominee for History of Violence shows off her sun-kissed skin in a white Elie Saab gown with a cascading skirt.
PAMELA ANDERSON: WORST
The Stacked star looks relatively demure – but her gown's sling-like top fails to flatter her famous figure.
VIRGINIA MADSEN: WORST
The Sideways star is in danger of going over the top – literally – in a light blue gown with a plunging neckline.
MARIAH CAREY: WORST
Her album The Emancipation of Mimi is a hit, but Carey's too-tight, too-revealing halter gown is a miss.
