Kim Kardashian looked her buxom best at the launch of her very first fragrance at the Tao nightclub in Las Vegas on Saturday, February 27. The Tao, in Palms

Casino Resort, is one of Vegas' hotter places to land up. What better venue for the sizzling Kim to celebrate her entrance into the perfume world?

Kardashian wore a formfitting, low-cut beige-and-black number with matching black heels. She paired it up with hair worn down and neutral colors on the face.

While we think it's an odd choice of colors to wear to an evening event, we'll let it slide, seeing as she's usually on the money! Let's hope her new fragrance is too. Kardashian showed up at the party escorted by her mother Kris and celebrity publicists Simon Huck and Jonathan Chaven.

It's been a busy week for K-ster, who previously tweeted Olympic gold medalist Evan Lysacek, plugged her fragrance on the sets of QVC shopping channel and met up with beau Reggie Bush at the salon.

The fragrance, named simply Kim Kardashian is a heady mix of tuberose, gardenia, and jasmine and is packaged in a circular black bottle. It is available exclusively at Sephora retail stores and QVC.
