The designer's representative has confirmed that apart from the 33-year-old socialite, Kim's daughter North, 11 months, also wore a Givenchy by Riccardo Tisci dress, and West, 36, wore a Givenchy by Riccardo Tisci tux, reported Us magazine.
Tisci, 39, is a close friend of the bride and groom. He designed the controversial floral gown that a then-pregnant Kardashian wore to the Metropolitan Museum of Art's punk-themed costume gala in May 2013.
He also designed the plunging black cutout gown she wore during a headline-making appearance at Paris Fashion Week in October 2013. He also posed with little North in an adorable photo in November.
