Emma Stone is a vision in white!

The 28-year-old actress turned heads at the European premiere of Battle of the Sexes during the 61st BFI London Film Festival in England on Saturday.

She stunned in a gorgeous vintage-inspired Louis Vuitton gown with open shoulders, ruffled sleeves and silver detailing, finishing off her look with gold shimmering eyeshadow and a peach lip. The dress choice was quite fitting, as Stone was recently named the fashion house's latest ambassador.

Battle of the Sexes depicts the epic 1973 match between Billie Jean King and Bobby Riggs, who is played by Steve Carell.

At the premiere, Stone also posed with the tennis pro, as well as Elisabeth Shue and Andrea Riseborough, who stunned in an elegant red Ralph Lauren Collection dress.

ET caught up with Stone last month during the film's press junket, where she shared that her physical transformation was "addictive" and gained 15 pounds of muscle for her role.

"A lot of weightlifting, a lot of protein shakes," Stone confessed of how she bulked up. "I never did it before and I loved it."
