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.
Other high-profile stars in attendance at the event included Hailey Bieber, Julia Roberts and Amal Clooney.
Wilde's stylish ensemble comes after Florence Pugh, the lead in Wilde's latest film Don't Worry Darling, also stepped out in a series of sheer designs.

The actress, 26, wore a fuchsia pink tulle dress that showed off her nipples to the Valentino Haute Couture show in Rome in July.
Pugh wrote: "What’s been interesting to watch and witness is just how easy it is for men to totally destroy a woman’s body, publicly, proudly, for everyone to see."
She added: "Thankfully, I’ve come to terms with the intricacies of my body that make me, me. I’m happy with all of the ‘flaws’ that I couldn’t bear to look at when I was 14.
"So many of you wanted to aggressively let me know how disappointed you were by my ‘tiny tits’, or how I should be embarrassed by being so ‘flat chested’. I’ve lived in my body for a long time. I’m fully aware of my breast size and am not scared of it."
Reflecting on the uproar to Harper's Bazaar, Pugh said: "I was comfortable with my small breasts. And showing them like that – it aggravated [people] that I was comfortable.
"It was just alarming, how perturbed they were. They were so angry that I was confident, and they wanted to let me know that they would never wank over me. Well, don’t."
