Surprised no one has said Dickies yet.
Although a work wear brand that many people including skateboarders have worn for a long time, they really only had a specific skate program around 2000 for a while with people like Mike V, then seemed to drop it entirely, then came back with colabs with DLX around 2007-2008 with more 2010-2011 (Antihero and Spitfire x Dickies clothing which I still have) to now having a bigger skate team than ever before and way more of a focus on skate related clothing for the last ten years maybe.
Happy for anyone to fill in gaps and tell me anything else, or correct me if I got any of it wrong too.
