1017 ALYX 9SM’s rollercoaster buckle is an icon. From streetwear to high fashion, however you choose to look at it. And this season, the label partners with END. for the very first time, spotlighting the iconic hardware and its technical inner workings in the process. It’s given through the graphic at the chest of this white cotton tee, which depicts the buckle broken down into its composite parts in a never-before-seen way.
