Olivia Wilde gave her abs an open invite.

The actress and director, 42, made her entrance at the Los Angeles premiere of “The Invite” Wednesday night in a custom Saint Laurent gown with a deep midriff cutout.

The striking design also featured puffed sleeves, ruched hips and a voluminous taffeta train.

Stylist Karla Welch finished the look with Hanut Singh emerald and pearl drop earrings with diamond half moons and a matching emerald, diamond and chalcedony ring.

Wilde wore her blond hair pulled back into a sleek chignon, with glowing skin and a mocha smokey eye.

She posed alongside co-stars Seth Rogen and Penélope Cruz — who wore custom sky blue Chanel by Matthieu Blazy — and screenwriter Rashida Jones, who co-wrote the script with Will McCormack.

The film, based on Cesc Gay’s Spanish-language “The People Upstairs,” follows two couples whose dinner party spirals into stranger territory. It hits theaters July 10.

The “Don’t Worry Darling” director recently shut down longstanding rumors of an on-set feud with Florence Pugh, telling The Cut, “I have never had a screaming match on my set.”

She also opened up on “Call Her Daddy” about the breakdown of her nearly decade-long relationship with ex Jason Sudeikis.

“You can get to a place in a relationship where you stop engaging in the knowing of each other and the curiosity of each other, and you find yourself in a place where you’re like, ‘I don’t even know you,’” she told the host.

Wilde has been making a statement on the red carpet, too. She made her Met Gala return in May — her first time at the event since 2023 — in a Thom Browne column gown with a caged tulle bustle.

Skin-baring designs have become something of a signature for the star. She turned up to New York Fashion Week last September in a transparent Michael Kors bodysuit and wore a fully sheer Chloé gown to the Vanity Fair Oscar Party the same year.
