Inside Bella, Kendall, and Hailey's Bikini-Clad Vacation

What do you get when you mix Bella Hadid, Kendall Jenner, and Hailey Baldwin with a tropical destination? A lot of Instagram-worthy photos, for starters. The models and BFFs are currently on a chic vacation together, and the 'grams are more than a little envy-inducing.
