Meanwhile, in another photo, the 19-year-old reality star shows off her curves, with a full-body shot of herself in a skintight gray crop top and matching sweatpants.

When it comes to casual wear, Kylie appears to have similar taste to Dream's mother, Blac Chyna. The 28-year-old model, who's rumored to have split from Rob, rocked a similar look on Snapchat.
