We've spent more hours than we'd like to admit scrutinizing Kendall Jenner's outfit choices. Sure, we may know a bit more than necessary about the pieces she's partial to (like her Re/Done jeans and Givenchy sunglasses). But, we've also noticed that Jenner has a definite uniform ; and while the labels on her clothes may change, she definitely sticks to certain formulas when it comes to putting looks together. Jenner confirmed this long-held theory of ours this week in a five-sentence post on her app titled " The Secret To My Casual Uniform ." Finally, the 20-year-old model lays to rest all those pesky, unverified, unofficial rumors regarding how, exactly, one must dress to cop her style. So, here's the definitive formula, according to Jenner herself: Wear a rocker tee or crop top, a pair of leggings, and a bomber jacket. There we go. The defense rests. If you follow Jenner's off-duty style, this will come as no revelation: She's been hashing and rehashing this athleisure-inclined outfit for years. (Friend and admitted outfit-matcher Gigi Hadid has exhibited a soft spot for this formula, too, with her style record). We get why: It's not only super-easy to replicate, but, as Jenner wrote, it's "comfortable-cool and ready to go anywhere."
