And here's the photo. This is a Belle Epoch mini top hat in 'mink' long-nap felt, with matching veiling, a large gray/green cockade, and pheasant feathers. I remember this hat very well, it was a joy to make, the colors are really subtle and were fun to work with. I love how happy the lady looks wearing it!
Here's a link to the full slideshow.
The hat was purchased earlier this year, perhaps specially to wear to the parade, from ADS Hats in San Francisco.
