Kim Kardashian recently got candid and opened up about using her sister Kourtney Kardashian’s money while opening their Dash boutique in 2006.

During her new 11-lesson series on MasterClass, the 45-year-old American media personality and socialite shared some tips and revealed “how she took bold risks and built billion-dollar brands.”

According to Page Six, Kim walked down memory lane to 2006, when she launched the Dashed boutique with her sisters Khloe and Kourtney in Calabasas, California, which later became a fixture in the early seasons of their hit E! reality show Keeping Up with the Kardashians.

The SKIMS founder went on to recall the financial struggles they faced while setting up their family business, which made them use “all of the inventory” on a credit card in her eldest sister’s name.

“We were able to get a credit card, first solely in Kourtney’s name because she had the best credit,” she said, recalling that she and her sisters did not have a history of “being able to pay vendors back on time” and for that reason, they “had to pay for everything upfront.”

“We would pay just the minimum every month when the credit card bill would come. This is probably the worst advice because you probably should be paying your credit card bill off, but we just didn’t have the money,” Kim recounted.
