December 16: The Countess of Wessex attended the Passing Out Parade at the Britannia Royal Naval College, Dartmouth. For this event, she repeated a black felt hat with wrapped crown, sidesweeping brim and stacked satin double hatbands. The hat’s original feather pinwheel trim was replaced with poppies for Remembrance Sunday service in 2009 and is now adorned with small felt twists.
Royal Hats 
I have to agree that the Queen’s blue beret is a standout. What a glorious color! The motion of the trim adds some drama.
Kate’s pillbox is a good working hat, and the color is lovely.
I love that Sophie is renovating an old hat and wish more royals would do the same. The new twists don’t pop like the original pinwheel, but make the look more versatile. The poppies were a mistake — so oversized.
Zara’s hats were beautiful.
Queen Camilla definitely wins this group for me with her royal blue beret at the South Africa state visit. It’s great to see her in a newish bright color for fall/winter, and the trim is well balanced on this one.
I also liked Zara’s outback fedora worn at Cheltenham and enjoyed seeing her hair down as well for something different. Kudos as well to Mike for his great outfit and cap, not to mention color coordinating his nails!
