Shop Celebrity Style: Mary Kate Olsen stayed close to her sister on the red carpet for the Elle Style Awards. The twins received the 'Style Icon' Award, which was much deserved proven here by Mary Kate in this all black Lanvin ensemble. Her Lanvin long sleeve dress was altered from the runway to feature a sheer cascading hem. Mary Kate carried Proenza Schouler's 'PS1' leather pochette to complete her stunning look.
