A fashion face-off was averted between “Scandal” star Kerry Washington and supermodel Iman the other night at Il Buco Alimentari. Elle mag and Tod’s hosted a dinner for the actress, who’s on the cover of Elle’s June issue. Washington wore a sand-colored Lanvin dress. Iman was overheard saying she was about to wear the same dress, but changed her mind at the last second and went with a white bustier top and pants, after taking fashion advice from her daughter.
