This is the Regency chapeaux I started at the Genesee Country Village and Museum’s War of 1812 and Jane Austen event. It turned out to be one of the largest pieces I have done.
The high crown is firmly sized, while the shaped brim is lightly sized for flexibility if you want to add a ribbon over it. The brim dips on each side, while flipping up in the back as several fashion illustrations show. Creating the curves of this hat were very fun.
The hand sewn plait is a supple Milan straw. The brim is fully wired.
The numbers you’ll want to know:
Inside the crown is 23″
Side to side – 14″
Crown height – 6″ high
Brim depth – 4.5″ in front.
If I Had My Own Blue Box: 
I really like the curve on this one. It has a nice delicate and graceful flare/attidude. 🙂
