Kardashian West stunned the crowd on the red carpet, wearing a sheer black lace Givenchy gown that showed off her new slimmer body. Its plunging cleavage and long hemline stood out, as the 35-year-old reality star kept her hair pulled back and her makeup light. By her side was husband West — who was understated in a long black zip-up jacket, Adidas track pants and white sneakers. The 39-year-old rapper took the stage later in the evening at the event — even pulling up the lady of the hour Roitfeld to the stage for a singalong. “I’m so excited,” Kardashian West told PEOPLE about the performance. Kris and designer pal Tommy Hillfiger lent their voices to the performance as well. The 60-year-old Kardashian matriarch looked glamorous in a figure-hugging red lace number with bold red satin belt. She kept a green army jacket over her shoulders. Splash News Online.
