We've heard about couples who start to unconsciously dress alike, and it looks like besties Kim Kardashian and Ciara are starting to fall into that habit as well.

Kardashian gets credit as the originator, stepping out in a voluminous black minidress from French label Carven's fall 2010 collection while in Paris on Sept. 16. The curvy bombshell paired the poofy and belted frock with leopard-print Christian Louboutin booties, gold studs and a quilted Chanel bag.

On Oct. 25, Kardashian's gal pal Ciara rocked the exact same ensemble at the New York City premiere of 'For Colored Girls,' save for the fact that she had no purse and her leopard booties came in a slightly larger print.

Because the women are so close, we've got to wonder if Ciara might be wearing one of Kardashian's designer cast-offs.

In any case, it doesn't look like the matching outfits spurred any hard feelings between the two. On Oct. 26, they were arm-in-arm at Ciara's 25th birthday party, both wearing skintight dresses.
