Kendall and Hailey looked like the models they are, decked out in high-end labels. Kendall wore a newsboy cap over her short bob, a denim jacket and Vetements stiletto sock-boots. Kendall was resplendent in Gucci -- a tee, backpack, army pants and bright red heels with a scarf wrapped around her head.


Meghan Trainor was there with her boyfriend Daryl Sabara. Paris Jackson attended with pals -- the young daughter of Michael Jackson was wearing a blush-colored peasant skirt, a belly-bearing top and lace-up boots.
