Lawks!
As I was a skint yoof I used to sew zips into my tesco jeans that I'd dyed black and purple and made into drainpipes. My needlework wasn't very good, but it was meant to be DIY punk! I even made my own bumflap out of a particularly vile green acrylic tartan material then scrawled "Slits" on it in fluorescent orange paint.
By contrast, mine and Swamp's mate (the only other school punk) had a rich dad who bought him a pair of real bondage trousers from XClothes, and real leather jacket with Ruts painted on it... We always sent him to the bar.
