I didn't see this thread the first or second time around. As others have pointed out, much of this depends on region and court. Where I've lived previously, jeans wouldn't be my first choice if I had other options.
Where I'm living now, showing up on time and performing civic duty as instructed shows all the respect anyone needs from a juror. A co-worker I've never seen in clothing that isn't stained or torn or worn through or sagging (or several or all of these, and never in flattering colors), nor with freshly washed hair, was chosen as jury foreman. He's one of the smartest, kindest, most earnest people I know, and that's what mattered most in that particular setting. The case went on for six weeks and the court provided fast-food lunches, same order for everyone.
