It’s hard to believe that it’s been over 10 years since we first met Kourtney Kardashian on ‘Keeping Up With The Kardashians.’ Over the years, Kourtney has completely matured into a proud business owner and mother-of-three who has tried more discreetly to keep her life a bit more private. But before all of this happened, Kourtney was the eldest of her siblings and was known for her work with her sisters, Kim and Khloe.

The trio opened a Dash clothing boutique in Miami and began to grow their businesses, branching out into fragrances and trying new things along the way. Kourtney, like her sisters, also became a trendsetter with her evolving sense of fashion and daring and dramatic looks! But Kourtney has always remained true to herself, especially after welcoming her three kiddos — Mason, Penelope, and Reign — with her former partner Scott Disick. Now, we’re taking a look back at her incredible transformation over the years from reality TV star to mother-of-three and business owner! Check out the rest of the gallery for more photos of Kourtney over the years!
