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 Kim 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.
The Italian fashion guru had also compared North West's mother to the late movie screen siren Marilyn Monroe.
