Her sister, Kylie Jenner, and older half-sister, Kim Kardashian, were also present, as was her mother, Kris Jenner.
Kris Jenner wore a white gown and coat by Oscar de la Renta, while Kylie turned heads with her own white dress that resembled a bridal gown.
Kardashian, meanwhile, turned heads in her sheer silver gown with lace floral and leaf accents.
However, fans were confused by her choice of grey sweater around her shoulders.
