The level of creativity when it comes to denim is off the rails, and almost nothing surprises us anymore. A pair of jeans that are essentially made up of a handful of patches? It's probably happening. Jeans that have a cut-out waistband and hems so long you'd need a friend to hold them up for you? We're sure someone sent those down the runway. The point is: Denim is no longer just denim. What once was a simple counterpart to a plain white tee and sneakers is now a clothing category all its own that's exploding with trends.
