While Fremar’s clients expect a fashion-forward proposition from the stylist, there are also a number of practical considerations at hand. For instance, Moore wore Chanel to accept her Academy Award for Best Actress in 2015. (The actress has no financial relationship with the house.) “We felt that it would be nice to be loyal,” Fremar revealed. “It’s nice to choose a brand that will support you, that has nothing to do with any monetary exchange.” To help Fremar and Moore choose the right gown, employees of Chanel hand-carried multiple looks from Karl Lagerfeld’s Spring 2016 couture collection to New York for Moore to try on. They settled on a black lace corset dress with a structured top and embroidered straps, inspired by a similar look from the collection. While the piece was multicolour when it was presented at Chanel's couture show, Lagerfeld created a black version specially for the actress, encrusting a layer of lace and organdy with 1,500 Swarovski diamond silver-shade stones cut into geometric shapes. After the stones were embroidered onto the dress, they were completely covered with frayed-edge black silk tulle.
Lagerfeld, who has built a congenial friendship with Moore over the years, altered the original design for the actress, taking the requests of her and her stylist into consideration. (For instance, along with changing the colour, he lengthened the gown so that it would hit the floor.) “Chanel doesn’t usually custom make clothing, so it feels really special and it is a statement that there is a relationship there,” said Fremar. “They have a mutual admiration. It’s a nice collaboration.” The dress was fit on Moore’s body a total of four times and required 500 hours of work and 22 people to complete.
