Khloé Kardashian's brand of denim, Good American, has proved immensely successful, but she didn't always know whether it would be.
The Keeping Up With The Kardashians star was anxious about the launch of one of her biggest ventures without her famous sisters.
On the latest episode of the reality show, the 32-year-old opened up about her nerves and being known as the "failing sister".
"I know we're not necessarily competing against each other, but still, I have always been known as like the fat sister," she said. "Now that I'm over that I don't want to be known as like the failing sister."
The star then went to younger sister Kylie Jenner for advice because of her huge success with Kylie Cosmetics.
"Do you know how scared I was when I first dropped my lip kits?" Jenner, 19, said. "I never would have imagined. There really is no trick, though. It never stops because you did this from scratch and you're passionate about it."
Khloé did eventually launch Good American to great success, selling out on the first day.
"Having people come up to me and express their gratitude is so overwhelming," she said. "I genuinely feel like crying tears of joy. I feel I am dreaming, but I'm living my dream. This is why I did this. So, f--k the sales. At the end of the day, this is what matters, that I'm making people feel good about themselves again."
