Yeaaars ago I used to use a visual kei import site called "Hammerhiroko" but they ceased to exist like literally about a decade back. Now I mostly hit up like random stores when i'm out in London - if you ARE in London, I highly recommend Gong Nong Bing Vintage in Soho, and if you're by Crystal Palace anytime, the Bambinos junkstore and Zoop Retro at the Hayne's Lane Market are enormous sources for me. The key thing tho is just.... be open to weird shit, and be like uninterested in brand value or even pretending to know anything abt clothing quality lol. My wardrobe is a mix of like expensive souvenir jackets and karakuri tamashii jeans and then just like... a random literal halloween prop or a shirt I bought off ebay for $3 that has cool holofoil or a trashy dragon on it. Look for anything from everywhere. Sometimes you really do just need to google "gold metallic jockstrap" and buy the first result that shows up that's cheap (Although that said the last gold metallic jockstrap I bought was from a store in Soho for like... quite a bit lol).
The key thing is - abandon shame, literally just throw on whatever looks cool to you and own it. That sounds very facile and trite and is easier said than done but it's absolutely true. if all else fails, a big all over print graphic tee and black drop crotch pants never fails
