The supermodel donned the outfit first at the 2009 American Ballet Theatre Fall Gala in New York, and looked sensational.
Eva Green then sported the same frock at the Cracks film premiere at the 53rd BFI London Film Festival in London.
Eva went for vintage curls and a contrasting shade of lipstick, whilst Iman teamed the outfit with a sparkling bracelet and black clutch, and matched her lipstick perfectly to her dress.
Whilst both ladies can pull the look off, we think Iman oozes Hollywood glamour with her glowing skin and shiny locks.
