I have two Chanel hats. This one is from the 70s. The style is similar on both. This hat has a larger bow on the front, assuming the label is at CB. It does not have a Chanel label, but is the same fabric as the suit.
Here is the second hat-early 1960s. The style is more or less the same, the bow is smaller and in the back--I think. There is a mark on the headband opposite the label. I assume the mark indicates CF. What do you think? Oops, the photos are too large. I also have the matching jacket and skirt, but they are in very poor condition. Oops, my photos are too large. I'll take them again tomorrow.
I'm in LOVE!!!! I know Barthet did hats for Dior, did not know (or have forgotten) that he also did them for Chanel.
