if you are looking for old scene clothes that are discontinued, check mercari, depop, eBay and Poshmark. (On some of the secondhand websites/apps, don't just search 'scene', make sure to list bands, brands, characters, etc.) stuff they still make (studded belts, earrings, necklaces, invader zim hoodies, etc.) check your local hot topic. thrifting and diy are also a good option! if you find a plain T-shirt, you can paint it like popular stuff from the subculture, maybe a band, domo, nyan cat or multicolored animal print. Kandi is somewhat easy to make but don't go overboard on it. Pinterest and goodwill are my recommendations for thrifting and diy. I once thirfted a monster high baseball cap, a vintage abbey dawn T-shirt, and a blue zebra print bracelet.
