One of the questions that I’m asked is “do I have to dress up for jury duty?” The answer is: no.
When we interact with jurors we are completely interested in what a prospective juror is telling us. What someone is wearing never factors into the equation.
Wear jeans. Answer questions honestly.
Here’s the official guidance from the Judicial Branch:
Decorum is maintained in the courthouse and jurors should dress accordingly. Shorts, t-shirts, or clothing containing offensive language or imagery are not permitted.
And whatever you are wearing, understand that the lawyers, judges, and court staff are very grateful for your service.
