Taylor Momsen has quickly established herself as one of young Hollywood’s hottest trendsetters. The Gossip Girl wore this oversized sweater dress over black nylons (no rips!) to the Clinique and Teen Vogue’s Fresh Faces Tour event in New York City this week. She almost got the look, but chose clunky booties which clashed with the sparkling gold ball pendant around her neck.

Victoria Beckham paraded around London in this black and white graphic printed dress, which is very similar to those in the Spring 2010 collection she debuted at New York Fashion Week earlier this month. The style icon cleverly belted her unbuttoned black cardigan with a skinny black belt, accentuating her tiny figure. She offset the busy graphics by accessorizing on the light side, wearing simple black heels and delicate bracelets. She finished the look with a luxurious Hermes bag.

Supermodel Agyness Deyn enjoyed a night out with her friends during London Fashion Week, in this half leather, color blocked dress…or is it a vest? The leggy ex-blonde (love her new dye job!) could have pulled it off, but opted to wear these confusing platforms, which were just too much.

Blake Lively owned the red carpet at the launch of Anna Sui for Target “Gossip Girl” Collection in this white pencil dress, accentuated with a hint of black. Choosing black and white bangles and studded black stilettos, she aced the style test!

Miley Cyrus, another young trendsetter, displayed a playful take on the black and white look while she was out to lunch with her friends in Los Angeles, by adding a little rock and roll! Miley paired a simple oversized t-shirt with a tight black mini, accessorizing to the max with chunky jewelry, black motorcycle boots, and a gigantic Chanel bag.

Leave it to Paris to get dressed up for a trip to the grocery store! While running errands, the heiress sported a feminine black and white dress and patent leather heels, accessorized with chunky rings and a necklace.
