Susan Reed: Headdress Classification
Flat Hat
a usually brimmed hat with a soft crown constructed as a circle pleated into a brim or knitted to shape. When the crown is made to lie flat on the brim, it looks like a pancake on a plate and has a roughly triangular silhouette. The brims project perpendicularly from the head opening, but a particular section of the brim may be folded up or down.
Variations
* Crown lies flat on the brim
* Crown is raised so that join between the brim and the crown can be seen
* Brims that go completely around the head opening
* Partial brims
* Split/slashed brims
* Overlapping split/slashed brims
