Kendall Jenner & Her Sisters Shop in St. Barts!

Kendall Jenner rocks a high slit dress while on vacation in St. Barts on Monday (August 17).

The 19-year-old supermodel was joined by her sisters Kim, Khloe, and Kourtney Kardashian, as well as her mom Kris Jenner. Kylie was not pictured here, but she was in Montreal for her birthday party the day before!

The Kardashian family is known for their fun annual trips – we hope we get to see footage on Keeping Up with the Kardashians!

FYI: Kendall is wearing a Zimmerman look.
