Ky, as usual, showed off her tiny waist in a black crop top and super baggy pants.
And it looks like she finally went back to her natural hair color! No more highlighter locks for Kylie.
Kendall was also spotted at the Los Angeles studio rocking athleisure and a Louis Vuitton backpack.
The runway model sported a tight Adidas crop top sans bra. We're totally digging the bright red lip.
