Royal Hats 
If we can go non-royal for a minute, I particularly liked the hat worn by Britainy Beshear, Kentucky’s First Lady, at the Kentucky Derby the other day. The hat worn by Lila, their daughter, was also interesting, but I thought a little too mature for her.

What a great percher! I’d love to hear from everyone what other hats at the Kentucky Derby stood out for you!
In other non-royal hat news, reader Lesley shared this article about the annual NY “Hat Luncheon” which saw some gorgeous hats!

Love that new black Treacy hat for Máxima, although sad we weren’t given better views of it. Hopefully we’ll get to see it again this fall/winter.
Did Mother’s Day (for those who celebrated/observed it) bring any hats out for my fellow readers? I spent the weekend settling into my new apartment, which involved a lot of organization for my hat and book collections.
The hat is gorgeous and it has the kink in the brim that seems to be popular with QEII. I think another 1-2″ on the hem might have been better and the top button fastened to show off the beautiful neckline.
Maxima dressed in black for memorial services, funerals etc is almost the only time I like her daytime outfits. They’re much more pulled-together and simply elegant. The outfit worn when she attended the service at the Cenotaph in London several years ago was one of her best.
These hats also caught my eye this week:
I love this and the outfit.
