For years when choosing what attire to wear when gigging ( rock bands ) I’ve always worn a T-shirt mainly black of course !!
As a returning bass player we do tend to dress smarter I find or have an individual style on stage, ie hats for example
I’ve now changed to wearing long sleeved shirts ( making sure buttons are not metal ) and I think it looks more in keeping with mature bass players ..
So for you mature gigging bass players have you left behind the humble T shirt for something smarter on stage ?
