Why would it be utterly inappropriate this day and age?
I'd like to try a response here.
It's a parliamentary event.
The ultimate symbol of monarchy is "the crown" represented by the Imperial State Crown which is present.
Of course the monarch has the right to wear that crown.
My guess has been that the King will not wear it primarily for comfort reasons.
Re "this day and age" I think the dressing up is seen as just that. The trappings of ancient traditions no longer make sense, except to a few of us.
