Kendall loves her Calvins! Reality star-turned-runway model Kendall Jenner took to Instagram in her Calvin Kleins on Wednesday to show off her killer bod' and classic undergarments.

Along with the body-baring pic, Kendall wrote, "it's 68 degrees, and there is a 30% chance that it is already raining," which is a line from Mean Girls.

It's been a whirlwind week for the 19-year-old. On Monday, she lit up the red carpet to the British Fashion Awards in London. On Tuesday, the tallest Kardashian walked the runway in the Chanel Metiers d'Art Collection 2014/2015 in Salzburg, Austria.

Looks like she didn't get enough of showing it off on the catwalk!
