Could Meghan wear the Cambridge Lover's Knot tiara (now usually worn by Kate and worn by Diana) to a function if Kate selects a different tiara or does not go to the function? In other words, who gets first pick for selecting what royal jewels to wear to functions? I would call 'dibs' on certain pieces and wear them all the time so that the other sister in law would not want to wear them. I guess that is why I am not a princess.
