I've changed jobs since last addressing the topic. I now have to wear dress slacks, dress shirt, and a tie. I don't have to wear a jacket around the office but do need to have one on hand in case I get pulled into a meeting with an attorney. I got use to it pretty quickly. Casual Fridays let us lose the tie.
Really, the only pain is to warm up the iron to knock the wrinkles out of my shirt in the morning.
