The 30-year-old star - who runs fashion chain D-A-S-H with sisters Kourtney and Khloe - admitted she is in awe of how "glamorous" the 'On The Floor' hitmaker always looks.
She said: "I'm inspired by Jennifer Lopez. I really like her style. She's really glamorous and always really well put together."
While the reality TV beauty - renowned for her curvaceous physique - likes a "simple" looks when it comes to her style, she thinks she looks "pregnant" in unflattering, baggy styles.
Kim added to Britain's OK! magazine: "My best look was a one-shoulder white dress I wore once and my hair was pulled back. It was quite simple.
"A baggy shift dress would make me look pregnant. It's not very flattering unless you're very skinny and tall."
Meanwhile, Kim confessed she is not against going under the surgeon's knife when she gets older, but has vowed to wait until she is 50 to properly decide whether a cosmetic procedure is right for her.
She explained: "Whatever makes you happy, go with. If it makes you happy to get some work done, go for it. My grandmother and mother have aged gracefully. I'm not against it, but I'll decide when I turn 50."
