to September 5, 1932, 88 years ago, and a very sweet tam-sporting Princess Elizabeth returning to Balmoral Castle from attending Sunday morning service at nearby Crathie Kirk with her grandparents. Queen Mary’s pleated toque hat is embellished with fabric leaves and a diamond brooch, an addition that also seems to be on her granddaughter’s tam, in mini version.

Royal Hats 
Great hats all around. I agree with Jimbo that the King’s tam merits attention. This photo shows the pleating and leaves on the Queen’s hat so well.
Regarding the thistle brooch: so many jewels, so little time.
I actually like grandpapa George’s hat also.
Here is the fascinating story behind Queen Mary’s Thistle Brooch, with great pictures of it. Apparently, Queen Elizabeth wore it for the 1st time as recently as 2010!

Replying quite belatedly, that was a very interesting article about the thistle brooch — thanks, Jimbo, for sharing it. Why do you suppose HM waited almost 60 years to wear it? It doesn’t seem possible that she forgot about it.
