Olivia Wilde stepped out in this covered up but sexy dress from Gucci last week.
She was in London for the premiere for new Hollywood film Cowboys and Aliens.
This romantic but cheeky gown is sheer and more provacative than what is usually seen on the red carpet.
Although the dress is in a '40s style, she has mixed it up with a '60s style hairstyle and flicked eyes.
For a similar look try this black star chiffon star dress from Dorothy Perkins with a white scarf.
