to January 18, 1960 and a visibly expectant Queen Elizabeth (Prince Andrew would arrive a month later) returning from Christmas break at Sandringham in a chic brimless hat.

The Queen looks so well and happy.
It’s furry!

Hat Queen would this hat be a blocked beret?
My first thought was: “It certainly looks to be a rigid shape so yes!”
Now that we’ve seen a closeup view above, it looks like more of a turban. Amazing how different a hat looks from different views!
That closeup really did make a difference in the texture of look of the hat! Thanks for answering.
If the color is accurate, HM’s coat is a deep maroon color with the white beret. This photo was apparently “la reine derniere photo avant le bebe.” (the last photo taken before the birth of Andrew.) I hope this is a legal photo.

That’s a marvellous find! It must have been the impending birth which led. To the early return from Sandringham too.
Her Royal Highness looks to be blooming with her condition. Marvellous to see!
You’ve posted a link (not hotlinked the photo) so all is good! Thanks for finding a colour snap.
That must be quite a rare picture, as royals avoided photographers in later pregnancy in those days. I rather like the jaunty hat.
