Kendall Jenner Stands Tall at Kardashian Kollection Launch Party

Kendall Jenner stood tall amidst the Kardashian sisters at the Kardashian Kollection Launch Party at The Colony in Hollywood on Wednesday, August 17.

The 15-year-old model, the tallest of the Kardashian/Jenner sisters, wowed in a body hugging Kardashian Kollection Women's Tattoo Print Dress with split neck and half sleeves. The thigh length dress had a front tattoo print and solid black trim on neck, cuffs and hem.

Kendall's shoulder draping hair was styled in loose waves with an asymmetrical parting.

Strappy black wedges and minimalist jewelry and makeup rounded her age appropriate charming looks.

The entire family, barring brother Rob Kardashian, was at the event: Kim, Kourtney and Khloe Kardashian, Kendall and Kylie Jenner; and the parents, Kris and Bruce Jenner.

Also present, Kim's fiance Kris Humphries. The couple indulged in some pre-wedding red carpet PDA, locking lips for photogs.

Kendall and younger sister Kylie left with their mother Kris Jenner soon after the red carpet photo session as the two sister are underage for the nightclub.

Earlier this week, Kendall and Kylie went out into the desert to shoot their upcoming spread for Worlds Most Beautiful 3D magazine, with photographer Nick Saglimbeni. Later, the two sister shared their photos on Twitter, looking totally transformed with voluminous curly hairdos.

"At my shoot with @nicksaglimbeni...here's a pic! :) http://t.co/SEO5Dld" Kendall wrote on August 15.

Earlier this month, Kendall was announced as the new face of Australian swimwear designer Leah Madden's Summer 2012 campaign, Pirouette, for which she posed in animal print bikini. Last year she was announced as the new face for Forever 21's Twist campaign.

The Kardashian sisters launched their new clothing line, Kardashian Kollection, in collaboration with LA based Australian designer Bruno Schiavi, who owns Jupi Corporation. The announcement of the upcoming clothing brand was made in August 2010. The clothing line is being launched through Sears stores across the United States and online at sears.com.
