The 38-year-old reality star admitted that her outlook on fashion "changed enormously" after meeting the 41-year-old rapper, who introduced her to designers such as Riccardo Tisci and Alber Elbaz.
Speaking to People, she said: "My style has definitely evolved.
"When I met Kanye and he really started to bring me to Paris he introduced me to a bunch of people. I think one of the first people I met were [designers] Riccardo Tisci and Alber Elbaz.
"When I went to Montreal to the Mugler exhibit [in February] or when I went to the Alaïa exhibit with Mr. Alaïa [in 2014], I learned so much along the way from so many of the best people in the world. So my appreciation has changed enormously."
The 'Keeping Up with the Kardashians' star - who has children North, five, Saint, three, and 15-month-old Chicago with Kanye - went on to explain that her interest in fashion was sparked by her mum Kris Jenner, 63, and confessed to raiding her mum's wardrobe growing up.
She said: "When I was 16 whenever the time was coming for prom, I would go through my mom's closet -- it was always Mugler, Alaïa, Versace, Chanel -- she had the best wardrobe.
"She would always be really generous and share her things with us, like I always wore her Alaïa dresses to parties."
The brunette beauty added that she and her sisters - Khloe and Kourtney Kardashian and Kylie and Kendall Jenner - still take pieces from their mum's wardrobe.
She said: "To this day she saved so much of it and she's given some really cool pieces to me and my sisters. That was such a fun time."
