Reese Witherspoon and Kristen Stewart in Black and Nude, Allison Williams and Fergie in Red: 5 Holiday Red Carpet Trends (PHOTOS)
Reese Witherspoon showed off her slimmed-down post-baby figure (just ten weeks after giving birth, no less!) in an Elie Saab LBD with nude and black lace panels at a charity event. She paired the on-trend look with black pointy-toe pumps and a bright pink pout for a festive touch.
Also sporting nude and black lace again, Kristen Stewart countered Witherspoon's classic version by putting her own cool-girl spin on trend in a black-and-nude shorts jumpsuit, black Barbara Bui booties and tousled updo for a screening of On the Road.
Modeling another big trend for the holiday season, Alexis Bledel, Fergie and Allison Williams all got into the holiday spirit, donning red-hot styles at different events.
Putting a glam spin on crimson, Fergie donned a sparkly red Monique Lhuillier mini dress, while Williams' went for a three-quarter hemline in a sparkly L'Wren Scott black-and-red zigzag sheath.
Showing us how to work pastels in winter, Amanda Seyfried took a break from promoting Les Miserables to attend a charity gala in London. After her dramatic black-and-white look at the film's London premiere, she went with softer look in a watercolor Alexander McQueen gown.
