The female cast of the CW's 90210 has some seriously enviable hair and Jessica Lowndes, without question, is one of the front-runners.

At the Teen Vogue Young Hollywood Party sponsored by Coach in Los Angeles on Friday, Lowndes traded her signature style (she usually wears her dark auburn locks styled in glossy, cascading waves) for a slick-backed bun that showed off the scoop design of her strapless mini.

The 22-year-old actress accented the tight, center-parted 'do with a french braid on each side that wrapped into a bun at the nape of her neck.

She paired her Camilla and Marc 'Sallow' dress with red Giuseppe Zanotti pumps and a bright scarlet lipstick to match the polka dot print in her cream-colored frock.

The Canadian beauty could have just thrown her hair into a ballerina bun, but that would have looked too formal. We love that she tried out a fun, young hairstyle for the teen mag-sponsored event, because if you can't show your girlie side there, where can you?
