Whether you're a defendant, witness or plaintiff, the best bet for a court appearance is to wear conservative business attire, something very similar to what you'd wear to a job interview. This means a suit, dress shirt and tie. Keep in mind that the courtroom is formal and serious, and that most judges are conservative and expect you to show respect for the court - not only in how you act, but also in how you dress.

When in doubt, go traditional
Choose a conservative suit color, such as a navy, charcoal, black solid or pinstripe. Pair this suit with a dress shirt in white, ecru, oxford blue, or French blue, and select a coordinated tie. Finish off the ensemble with a pair of lace-up dress shoes and a matching leather belt.

You want to avoid loud colors or anything flashy. Don't wear a leather jacket, and remember that any coats or hats should be removed when you enter the courtroom as a sign of respect.

What if you don't have a suit?
If you don't own a suit, a navy or black blazer with dress slacks, combined with the accessories referenced above, can be an acceptable substitute. As another option, if neither a suit nor a sport coat is possible, opt for the dress shirt and tie, combined with dress slacks. It's not ideal, but it'll do in a pinch.

No jewelry
The no jewelry rule is especially key if you are trying to win a monetary award in court. A judge or jury may be less sympathetic and award a smaller settlement if you look like you've got money to burn. It shouldn't matter, but it often does.

Remember comfort is key too
Try to choose clothing that you feel comfortable in. Appearing in court often means a lot of waiting around, and if you are uncomfortable, you may appear shifty or nervous, not the impression you hope to convey.
