Ok, this thread is a staple in guitar forums. It’s been discussed all around, over and over, and there are always lots of jokes in replies but it’s fun. I think in about 90% of the gigs I’ve played I’ve worn blue jeans, brown boots and a plain black or white T-shirt. The only stuff I put on is a silver wristband in my picking hand, a chain attached to my wallet and a burgundy colored flying bandana in my rear pocket it’s good to have one when you sweat too much or spill booze). If the venue is more formal, I put a black button up shirt, and it it’s less, I wear Converse Chucks (been using them since the early 80s IIRC, love them). Oh and I don’t ride bikes, but I often play gigs in biker clubhouses and motorcycle related meetings. Then instead of a leather vest, I put a black suit vest over the white tee.
