Why Is Kylie Jenner Wearing Kendall's Old Underwear?

Kendall and Kylie Jenner have the nearest dress size among the siblings so they can easily wear each other's clothes, but it seems that the Victoria's Secret model will only allow her sister to have the most “uncomfortable” stuff.

Being a part of the Kardashian-Jenner clan definitely has its perks, except if you're the youngest of the family and you don’t see eye-to-eye when it comes to borrowing clothes with your older sister. "I let her borrow whatever she wants. She always comes through and is like, 'I need an outfit please,' and I'll let her borrow whatever," the 18-year-old reality star told People Style.

"And then I go over there, and I'm like, 'Kendall, I need a pair of sweats to go home,' and she'll give me the most uncomfortable old underwear, the worst sweats you've ever seen and anything that's so bad and old and small. And I'm like, 'You're so mean'," she added.

But Kendall revealed that all of her sisters are "super generous" when it comes to sharing their items, "minus Kylie."

"Kylie and I always fight over clothes," she noted. "It's a problem. It's because we grew up together and we just grew up fighting over clothes."

Their previous closet war was documented on their show Keeping Up with the Kardashians, when the sisters were getting ready for the ESPYs. Kendall asked Kylie if she could borrow a dress for a party after the show but Kylie refused, and their feud escalated quickly.

With all their money and endorsements, these two sisters are still feuding over clothes and it doesn’t look like it’s dying down anytime soon.
