The 32-year-old gave birth to her first child with boyfriend Kanye West June 15 and the socialite is in the habit of buying same design of clothes for the baby, reports femalefirst.co.uk.
"Kim ... spends all her time shopping online for Nori (North West). She mostly buys white items, and she buys multiples of the same thing because they get dirty so easily, Star magazine quoted a source as saying.
"Many of the little designer dresses cost upwards of $600 a piece, and Kim will buy 10 to 15 items at once. Kim spends more on baby clothes a month than many celebrities spend on their house payments," the source added.
It was recently said that Kanye is spending a huge amount to upgrade the security around his family.
