When it comes to matching sets, we generally ascribe to the school of Taylor Swift. But, Kendall Jenner's been offering her own lessons on the trend. The model's most recent foray into coordinated separates takes a step away from Swift's feminine, sophisticated ensembles, and instead leans to the side of comfort. To grab lunch with sister Kylie, Jenner put an athleisure spin on Taylor Swift's signature look. The 19-year-old matched her heathered sweatpants with a cropped, short-sleeved top in the same material. But, this wasn't an ordinary sweatsuit: On top of a shorter fit, Kendall's top came with a white loop-belt hem, which she matched with the shoulder straps of her backpack. Jenner took the neutral color scheme very seriously, from her black-and-white mirrored sunglasses down to her gray sneakers. Kendall Jenner already has many titles under her belt, from model to street style star to teen-we-want-to-grab-lunch-with-sometime. Now, she can add matching-set pioneer to that growing list.
