Kendall Jenner loves a challenging look — she favors the deepest plunge and the highest slits. So for her 21st birthday party last night, she went all out, wearing a dress that would cease to exist should there be a breeze.

Kendall and stylist Monica Rose sent designer Antoine Salameh reference images, and he took it from there. You only turn 21 once, y’know?
