Leighton Meester's Gossip Girl character, Blair Waldorf, shows off her Spring style in a floral Peter Som frock, bright nail polish, and a matching lip on set in NYC. The brunette beauty layers a zesty yellow peacoat over her dress, then slides on a pair of burgundy mary-jane Miu Miu pumps to create a new color pairing of yellow and maroon. A triple-strand beaded necklace, maroon Stella McCartney bag, and retro hairdo complete her on-screen style. Another more casual way to re-create this Gossip Girl's transitional color combo is by pairing cropped yellow trousers with a maroon sweater. Don't forget a pop of floral via shoes or a handbag to really nail this chic Spring mix.
