Olivia Wilde opted to wear a daring outfit to the second Annual Academy Museum Gala in Los Angeles on Saturday.

The 38-year-old actress and director bared her nipples in a sheer, sparkly dress at the film industry event.

Designed by Alexandre Vauthier, the silver long-sleeved, floor-length gown also featured a pink, feathered hem.

Wilde finished off her look with glowy make-up and styled her hair in glossy waves.
