I think if she will wear her crown, it will be on pnly the circlet without the arches etc. This way Queen Elizabeth wore the circlet of her crown a few times. Not sure but i think also to State Openings of parliament during her husbands reign. but neither she nor Queen >mary wore their full crown with arches for State Openings
