New mum Emma Stone rocks Louis Vuitton trouser suit for Cruella premiere

Emma Stone recently hit the red carpet for the first time since becoming a mother for the Cruella premiere in Los Angeles.

The Oscar-winning actress and husband Dave McCary welcomed their first child, a daughter, back in March, and Emma rocked a chic black Louis Vuitton trouser suit for the star-studded event at the El Capitan Theatre on Tuesday.

She teamed the tailored look with a white pussy-bow blouse, red handbag, and black pumps, and finished off her outfit with a show-stopping Louis Vuitton sword brooch.

The piece, which was pinned on the lapel of her blazer, is called the Les Armoiries brooch and features three types of gold as well as a pear-shaped yellow diamond, 110 yellow diamonds, and 41 white diamonds.

The La La Land star finished off the look with wavy auburn locks, and Emma's longtime hairstylist Mara Roszak wanted to bring out the natural texture of the new mum's hair to complement the "very French and structured" Louis Vuitton suit.

"Her hair has a slight natural wave that I like to enhance. It's long, absolutely gorgeous and healthy," she told People, noting that she used products from her own haircare line, RŌZ, on Emma's locks, beginning with the brand's Santa Lucia Styling Oil.

"(The oil) will never weigh the hair down. It enhances what is naturally there and adds shine, de-frizzes and defines," Mara explained, noting that she used a small curling iron to give Emma's curls more definition.

The star's make-up artist Rachel Goodwin complimented the look with bright cherry red lipstick and a slick cat-eye with diamante gems.

"What a way to come back together with my beautiful Glamily again!" she wrote on Instagram, alongside a close-up of the Crazy Stupid Love star.
