A mock Tudor period hat
Whilst the correct shape, the materials are wrong and proportion a little exaggerated, although I have no doubt people in the period did add lots of flashy bits to make them stand out.
This hat came as part of a job lot of theatrical medieval hats I purchased via eBay.
Perfect for your Shakespearian play.
"A horse! a horse! my kingdom for a horse!", said Richard not me but King Richard the Third at the battle of Bosworth, at least according to Sheakspear.
