The model – who’s back in the States after an appearance for Chanel at Couture Week in Paris – and her younger sister clearly put a lot of thought into their ensembles.
Kendall proved that a black dress certainly doesn’t have to be boring by slipping on a creation by Alexandre Vaulthier combining sheer fabric and patent panelling.
The 19-year-old added even more inches to her statuesque frame with a pair of Stuart Weitzman shoes.
With her mid-length hair brushed back behind her ears, Kendall displayed a sparkling pair of Harry Kotlar diamond stud earrings.
Kendall also dazzled in gems by Messkia.
She kept her make-up simple, opting for a couple of coats of mascara and a slick of nude glossy lipstick.
Kylie chose an equally dramatic look for the occasion.
The 17-year-old stepped out in a gold high-necked gown embellished with vertical rows of sequins. The floor-sweeping number was designed by Shady Zeineldine.
When it came to choosing accessorises, Kylie opted for towering Tamara Mellon sandals and a small rectangular Judith Leiber clutch.
Kylie side-parted her shoulder-skimming layers, favouring a natural-looking blow-dry with plenty of body.
She swept a metallic shadow across her eyes for a glamorous finishing touch.
The duo – who were joined by other members of their family including Kim, Khloe and Kourtney Kardashian – were visibly moved when Caitlyn Jenner took to the stage to make a speech during the annual ceremony.
Kendall and Kylie both appeared to have tears in their eyes as Caitlyn opened up about her transition.
‘I’m clear with my responsibility going forward to keep learning to do whatever I can to change the landscape of how trans people are treated – accepting people for who they are,’ she said.
‘You should join me in making this an issue for you too.’
