Kendall and Kylie Jenner arrive at the 2012 Race to Erase MS Gala held at the Hyatt Regency Century Plaza on Friday night (May 18) in Century City, Calif.

After walking the red carpet, the Seventeen magazine contributors headed backstage to change out of their pretty dresses and walk the runway for the fashion show.

“walking in the Race to Erase MS Gala and Fashion Show tonight! ???? #excited” Kendall tweeted.

Kendall and Kylie modeled looks from the Andy Hilfiger Andrew Charles Rock ‘N’ Roll Collection in addition to a presentation of the debut collection Authentic Icon, inspired by American Idol.

The night benefited the Nancy Davis Foundation for Multiple Sclerosis and its Center Without Walls program which continues to raise funds in order to provide treatment and ultimately find a cure for MS. Guests also participated in a silent auction before enjoying a dinner gala featuring live musical performances by Fitz and The Tantrums, The Tenors and David Cook.
