"Self-made Billionaire" claim is mostly Fake News
Just ran across this article on Yahoo which dedicates a lot of their gossip headliners to the Kartrashian brand. Turns out that the Forbes article labeling Kylie as one of the youngest Self-made Billionaires is pure conjecture with the only source coming from Kris Jenner and her management team.
On top of that, the company selling her branded name is only showing gross earnings of $330 million for a year. Anyone who understands business knows that all of that money is gross sales is not net profit.
