Kim and Kourtney Kardashian arrived looking very coordinated in Balmain metallic ensembles for the designer afterparty on Thursday night .
The 37-year-old reality star teamed her teeny outfit with strappy black high heels, while Kim stuck to perspex sandals and sunglasses.
Kim, who was accompanied by husband Kanye West, who despite his love of fashion, looked much more conservative in a pair of slouchy tracksuit bottoms, black sweater and gold necklace.
