Kim and Kourtney Kardashian rock revealing styles at 'The Promise' premiere

Leave it to Kim and Kourtney Kardashian to slay on the red carpet.

The reality star sisters stole the show at "The Promise" premiere at the TCL Chinese Theatre in Hollywood on Wednesday.

Kim, 36, gave us Egyptian-goddess vibes with her wowing look, which featured her new (and much shorter) locks in a sleek-straight style and a figure-hugging gold sleeveless gown that nearly hit the floor.

Kourtney, 37, opted for a more conservative look in a black suit with a deep-V neckline -- and nothing underneath -- that added a sexy touch to the outfit.

Legendary songstress Cher also hit the red carpet looking very sexy, wearing a black leather jacket with white embellishments and a nearly see-through top. Of course, the singer HAD to get a picture with the Kardashians, creating a photo that's truly one for the books!

Other famous faces also turned out to support the movie about a tragic love story set during the Armenian Genocide and final years of the Ottoman Empire.

Nina Dobrev, Christian Bale and Orlando Bloom were some of the major celebs in attendance.

Check out all the hottest looks of the night in the slideshow above!
