It's a lot. Because when it comes to style, these two were cut from the same cloth.
Skintight pencil skirt co-ords, plunging black dresses and sheer red carpet showstoppers – the sisters' matching tastes are uncanny. And they're the first to admit it.
Kim regularly admits she pinches clothes from her 17-year-old sister's wardrobe, while Kylie names Kim as her 'biggest style inspiration.' Aw.
It's not just fashion either. Kim nicked Kylie's short hair idea and went for the chop herself earlier this year, and when it comes to selfies? Well, it's easy to see where Kylie got her tips from.
They're two of the coolest style twins in showbiz, and we love them for their shared love of all things glam.
Here are 14 times Kylie and Kim WERE the same person...
1) The black bodysuit/red coat combo
Kim and Kylie didn't just opt for the same outfit; they did it on exactly the same night! Yep, as they both stepped out for (separate) nights out in New York City, the sisters both wore a black bodysuit with a statement-making red coat over the top. The only major different was that Kim's cover-up was a furry texture, while Kylie's was leather. Twinning.
