to the Epsom derby in June 1976 and a bumper brimmed hat in the most marvelous blue and green print worn by the Queen Mother. 1970s fashion gets a bad rap but wouldn’t you say, this is some of the best?!

Royal Hats 
It’s a great hat! It looks as though the pattern is woven into the straw? I wonder how the milliner got her to go with such a departure from her usual flower-laden style?
Love the color combo and that graphical pattern. I’ve never before seen this hat or any other like it on QM. I couldn’t find any other views, but if anyone else finds any, bring them on! It would also be interesting to see if the green is carried over into her dress/suit, or just the blue.
Matthew, I scoured the entire internet and came up with ONE other photo, but alas it is in b/w. (You’d think I had more important things to do during a pandemic, but i’d rather have some fun and do some searching for you.) Sorry to disappoint you, friend. I DID however find several other hats that were worn with the QM’s beautiful blue coat, as far as I can tell, and will share them if there is an interest.

Thanks, Jimbo! Believe it or not, I actually saw that photo when I was doing my own search, but in that small B&W format, I didn’t recognize it as the same hat. If you would care to post the photos of the same coat with other hats, I would love to see them — that was always my favorite color on QM, it suited her skin tones so well.
I really like that. Would like similar worn today.
I’ve never seen this one before – it’s fantastic. The Queen Mum was normally on floral patterns, so it feels unusual to see a graphic patterned hat on her. The use of the colours is great.
Wow, love to see a closer shot to see more
Beautiful!
