That's where sewing comes in handy though that may not be the best route for you. It's harder for straight men who aren't invested in the punk culture to up cycle old clothing into something they'd be willing to wear in public. As for me, I plan on taking an old pair of jeans today and turn them into bell bottoms. If I hurry I can wear them to the farmers market.
The only thing I have time to invest in anymore is Children's clothes. I'm not kidding for every 60 bucks I spend on each of them I have to buy 80 more next week after they've outgrown it! Plus my wife does that all the time with clothing. I don't see how the hell anyone has patience for it hahhaha I just throw it on and go. However I'm an avid collector of stupid shirts
