Kim Kardashian stepped out with her family to celebrate the opening of the Kardashian Khaos boutique at The Mirage Las Vegas.

Kim, Khloe, Kourtney, Kris, Kendall, Kylie, Rob and Scott Disick hit the red carpet to promote the new boutique at the swanky Sin City hotel. The Kardashian Khaos store is described as the first celebrity concept store of its kind, offering a variety of items, only available at Kardashian Khaos, including all the products that the Kardashian girls and Kris Jenner own, represent, market and endorse, coupled with exclusive Las Vegas souvenir items.

Kim opted for a leopard print mini dress with plunging neckline and some platform espadrilles. Kourtney, Khloe and Kris all opted for black, although Kris glitzed it up with some sequins. Kylie wore a shimmering ombre bandage dress and Kendall went with a simple navy baby-doll frock.

Felix Rappaport, President and COO of The Mirage, said, It's hard to think of a brand that embodies fun, energy and excitement better than the Kardashian brand. The Kardashian women have developed an unmatched international following and we're thrilled that The Mirage will be home to their first Las Vegas store, Kardashian Khaos. We look forward to a wonderful relationship with Kris, Kourtney, Kim and Khloe, and to welcoming their fans from around the world.

Kim looked happy as ever at the opening, smiling for the cameras and laughing with her sisters. The newly single 31-year-old told Us Weekly at the event that she is not looking for a man right now.

I'm really thinking that 2011 was a lot of learning lessons, Kim told the magazine. 2012, I'm just excited for the New Year and the new me.

She did add, I believe in love...always.

The Kardashians continued a whirlwind 2011 after being chosen as one of Barbara Walters' Most Fascinating People of the Year.
