Since she first started promoting the film, which she stars in as Sharon Tate, Margot has been channelling the late actress with her fashion choices and beauty looks, opting for breezy dresses and emulating the Hollywood glamour of the late '60s with her beauty looks and accessories.
For last night's event, Margot matched her tangerine orange dress with her eyeshadow and wore her hair out in loose waves. She accessorised with glitzy Chanel earrings and an Edie Parker clutch.
But it was what she wore to the after-party that really caught our attention. Later that evening, the Oscar-nominee opted for a more relaxed look, swapping her dress for a two-piece floral suit, part of Matteau’s Resort’20 collection, and Loeffler Randall gold heels.
She's not the only stylish celebrity to give the twin set the tick of approval recently, either. Both Priyanka Chopra and Sophie Turner were spotted in matching two pieces, which Victoria Beckham designed and then wore recently, too.
If these comfortable ensembles are going to become a trend, we're well on board.
