Kylie Jenner Poses In Underwear From Tyga's Crisp Line

When she's lounging around the house, Kylie Jenner wears Crisp boxers.

The 17-year-old reality star posted a photo on Snapchat Thursday of her wearing a white tank top and a pair of tight Crisp boxers . Her rumored boyfriend, Tyga, partnered with Crisp last year to create his own line of the men's undergarments.

Earlier in the day, Jenner was photographed wearing different clothing -- specifically a $300 pair of camouflage sweatpants from Bape -- while at the grocery store with Tyga in Calabasas.
