I wear a kilt daily, to the office, and on my days off. As someone who has had the experience of kilting up to go to work, the only advise I can give is to make your outfit as smart as you possibly can so that you put your best foot forward and look professional. That is what seems to work for me, my boss even told my once he would give me all the overtime I wanted provided a promise to wear the kilt. Best of luck with it.
