It has been a tumultuous year for Kim Kardashian, but you wouldn’t be able to tell that by the look of these photos! The reality star stepped out to celebrate the grand opening of the “Kardashian Khaos” store at the Mirage Hotel and Casino in Las Vegas, Nevada on Thursday, December 15th, 2011.

Joining her for the big event were siblings Khloe, Robert, Kourtney and Kylie & Kendall Jenner.

Kim looked radiant in an animal print mini-dress with a leather belt cinching her waist and a pair of platform, espadrille sandals that wrapped at the ankle. Sisters Khloe and Kourtney opted for black ensembles while younger sibs Kylie and Kendall kept their outfits fresh and fun.

Kardashian Khaos, a new celebrity lifestyle boutique, is the first celebrity concept store of its kind. The store offers a variety of items, including all the products created by the Kardashian girls including t-shirts, novelty gambling chips, a surprise beach towel, playing cards, private label make-up by Stila, individually designed scented candles and more!

In a joint statement, the ladies said “we’re thrilled to have the opportunity to share some of our favorite products and even one-of-a-kind items with our fans, and happy that Felix (Rappaport, President and COO of The Mirage) and his team have welcomed us to The Mirage. Given that Las Vegas is the number one destination for countless travelers from around the world, having such a big presence there is a dream come true and very special to all of us. We look forward to seeing everyone on our visits to the store.”
