The sisters wear similar outfits

Kim and Khloé Kardashian looked like twins at a party in New York last night.

The TV stars both stepped out in tight black dresses that flaunted their curves for the NBC Universal Upfronts event.

Kim, 33, shared a photo of the siblings standing face to face at the do on Instagram and joked about their shapely bottoms.

‘Keeks & Kokes #sisters #deeptalk #SheGotABigBootySoICallHerBigBooty,’ Kanye West‘s fiancée wrote.

Khloé, 29, also posted a cute shot of Kim checking her hair and make-up for her on the red carpet.

‘A little sister TLC by Keeks,’ Khloé captioned the picture.

There were some slight differences in the girls’ outfits – Kim‘s frock featured a deep V-neck that exposed her cleavage while Khloé covered her chest with some beige panelling.

It’s not the first time this week that the sisters have been matching.

Both Kardashians wore suede beige heels and casual jeans as they made their way through LAX airport on Wednesday.
