Kendall Jenner looked ready to walk down the aisle herself!

The 15-year-old model nearly stole the show at big sister Kim Kardashian's wedding to Kris Humphries on Saturday. For Kim's big day she got ultra glam in a floor length, ivory-colored mermaid gown by Vera Wang.

Later in the evening, Kendall, Kylie, and big sisters Kourtney and Khloe changed into matching white sweat suits, a source tells Us Weekly. Meanwhile the bride, 30, had a total of three dress changes throughout the night -- all custom made ivory gowns by Vera Wang. 

Although Kim and Kendall are BFFs now, there has been some tension between the sisters. On an episode of Keeping Up with the Kardashians that aired in June, Kendall accused Kim of pressuring her into modeling. "You knew from the beginning I've been scared to do runway," she huffed. "I really don't want to be here. I feel like you're doing this for yourself!"
