Simone Ashley showed up for the last few days of the 2025 Cannes Film Festival with one of the best red carpet looks of the entire week. But before she got down to the evening wear, Ashley chose two casual outfits to fit the South of France vibe.

The Bridgerton actor arrived in Cannes this week to attend the premiere of The Mastermind, which stars Josh O'Connor, Alana Haim, Gaby Hoffman, and more. Ashley was there to support the arts and arrived in style — literally.

Ahead of her red carpet appearance, Ashley was photographed walking into Hotel Martinez on May 22, wearing a matching skirt and button-down set from Prada. The miniskirt cascaded out slightly and was made of a shiny, iridescent material and matched the sleeveless open top. Ashley paired the set with a white bra underneath, along with a blue shoulder bag and rectangular sunglasses.

When it was time to step onto the red carpet, Ashley went all out. The actor was a showstopper in a Vivienne Westwood gown, made to perfection. The white ball gown comes from the brand's Spring/Summer 2025 collection and looked radiant on Ashley. The dress featured the signature Vivienne Westwood corseted top, along with two wing-like adornments that give the gown an ethereal elegance. The gown then balloons out into a ballgown-style skirt that hangs just above her ankles.

After walking the red carpet, Simone Ashley changed into a more casual look the following day. She headed out to Cannes wearing a vintage Alexander McQueen outfit from the designer's 2000 collection. The outfit included a matching strapless top and skirt. She paired the outfit with the same sunglasses, a black handbag, and black thong sandals.
