I just finished reading Margaret Rhodes' book, The Last Curtsy and in her story, she mentions attending a State Banquet for the King of Malaysia shortly after joining her aunt's household and mentions Queen ELizabeth the Queen Mother leant her one of her tiaras for the occasion. It made me wonder if there have been any recent examples of royal tiaras being "leant out" and worn by someone other than their owner (aside, of course, from tiaras regularly rotated amongst different members of the same family).
There is THIS photo of Reg Wilcock posing with Queen Elizabeth's lotus tiara after the Linley wedding, but any others?
I think I'm going to write to Mrs. Rhodes. Hopefully she'll be able to share which tiara she wore. lol
