Margot Robbie may have lost out on the Best Actress gong last night but the* I Tonya* star topped best dressed lists everywhere. The newly appointed Chanel ambassador wore a beautiful, off-the-shoulder gown by the French fashion house accessorised simply with diamond earrings and a miniature plastic clutch. Accompanied by her mother on the red carpet, the Oscar nominee kept her makeup simple and wore her blonde lob in loose, retro waves
Although Robbie’s old-Hollywood look appeared effortless, it turns out that the Haute Couture masterpiece she wore took a whopping 600 hours to make. Made by Chanel’s Creative Director, Karl Lagerfeld, the exquisite and detailed design featured a corset bodice with a band of crystal tubes, filled with Coco Chanel’s favourite flower, Camellias. According to InStyle US, the corsage and strap took 14 artisans 550 hours to make while the dress took 130 hours to assemble.
Despite the lengthy process, a PEOPLE report revealed that the strap on Robbie’s dress actually snapped off after she’d walked the red carpet. A sartorial disaster was avoided when Robbie borrowed a sewing kit from an assistant and mended the strap herself.
