Kendall's appearance at the fashion show came just two days after her younger sister Kylie hit the catwalk at Avril Lavigne's Abbey Dawn exhibition.
Kim Kardashian took to Twitter to praise her sibling's runway debut, writing: "Must be emotional today bc when Kendall walked out on the runway I almost cried! I can't believe she's living her dream at such a young age."
Sister Kourtney added: "@KendallJenner seriously strolled like a major supermodel down that catwalk tonight at the Sherri Hill fashion show. All I can say is WOW!"
Kendall has also posed for a series of print campaigns for Sherri Hill, which specialises in prom dresses.
