Both women dressed to impress during their time attending what is likely to be one of many prestigious fashion shows throughout the week.
Paris, 37, opted to wear a black and white patterned halter maxi dress with a pair of black boots. She had her blonde locks styled in loose beach waves and wore a glamorous makeup look.
Nicky, 35, went for a brighter look and wore a fun purple pant suit that consisted of high-waisted slacks and a cute blazer, which she wore on top of a pink silk blouse. The mother-of-two had her hair pulled back into a sleek high ponytail.
The girls also brought along their sister-in-law, Tessa Hilton, who is married to their brother Barron Hilton II.
Tessa, 24, wore a fitted white two-piece set and nude stilettos. She kept her short blonde hair in loose waves and rocked a bold pink lip.
