While thereâs a purely functional reason for layering, i.e. moderating our ever-fluctuating body temp (big thanks to our erratic heaters), thereâs also something artistic, even emotional, about this approach to dressing. At the root of it, a stylish pileup is the ultimate form of style self-expression. Layering is a power move that leads to endless combos and, most importantly, allows you to take something as basic as a band tee or as mainstream as a moto jacket, pair it with polar-opposite pieces, and transform it into a look that's so you.
