WATCH: Khloé Kardashian Fears Her Good American Jeans Won’t Be as Successful as Kylie Cosmetics

Khloé Kardashian was concerned that her Good American jeans wouldn’t sell as well as Kylie Jenner’s Kylie Cosmetics before the denim line had a chance to hit the market.

Khloé expresses this doubt to her sister Kourtney during their morning workout in the clip at the top of the page from Sunday’s Keeping Up with the Kardashians.

“There is so much stuff to do to prep for the launch of Good American and Emma [Grede, her business partner] made me really nervous telling me about this number and how hard it is to get to that number,” says Khloé. “Now, I’m nervous that I’m not going to make my investors and my business partner happy.”

She tells Kourtney she fears the Good American team won’t reach their sales goal because the number that’s been set is one that hasn’t been achieved before.

“I feel so nervous. Kylie sells hundreds of thousands of units in like, what? Three minutes?” says Khloé. “I know we’re not necessarily competing against each other, but still, I have always been known as the fat sister and now that I’m over that, I don’t want to be known as the failing sister.”
