The 33-year-old socialite, who welcomed her first child with rapper fiance Kanye West last year, said North likes to move around the house, reported People magazine.
"North has actually not worn anything designer yet! Kids get dirty. She'll spit up. She moves around so much. I saw this one cute dress that was USD 500 and I was like, 'Absolutely not!' I just want her in little leggings," Kim said.
The 'Keeping Up with the Kardashians' star, who is expected to get married this year, earlier revealed that her wedding to West is not going to be as big as people are imagining.
