What a gem! Mila Kunis stepped out to a Gemfields event in London and she could not have looked more elegant in her all-white ensemble, which showcased her sexy post-baby curves.

The Black Swan actress, 31, who welcomed daughter Wyatt Isabelle with fiancé Ashton Kutcher on Oct. 1, 2014, slipped her body into a blazer-inspired Antonio Berardi sheath dress, complete with a double-breasted bodice, which highlighted her slim figure and ample cleavage.

To accessorize the frock, Kunis added matching marshmallow-hued pumps by Jimmy Choo. And as it was a Gemfields event—the brunette beauty is a spokeswoman for the jeweler—she also rocked one of the brand’s new Mozambican ruby-studded diamond bracelets and ruby earrings.

Rounding out her look, the That ’70s Show alum styled her hair into loose waves, brushed over one shoulder, and added a deep crimson lip—the perfect complement to her jewels.

Since giving birth last fall, the actress hasn’t left her little girl’s side, only stepping out for the occasional movie premiere and music festival. As she confessed in a Reddit Q&A last month, that’s exactly how she likes it. “I’m proud to be a stay-at-home mom,” she wrote. “I want an ecofriendly car, I want to compost everything, because I want the world to be better for her.”
