Hello Dorothy Waterman,
I agree with the others that you will want to wear good fitness clothing that would pass in court.
I would not wear more jewelry than a watch and small earrings, no perfumes or makeup, either. Fresh and clean always wears nicely.
I like to wear a short sleeve polo underneath in case I am asked to demonstrate some moves.
Good luck with your interview; let the real you show through with confidence.
