Plush and metallic trim formable hat from Elope. They will fit just about any normal adult head, including ladies, as it is of wired plush fabric and not stiff felt. With wired edges for shaping, you can even form it into a bi-corn or Barbosa or Musketeer if you so choose.  Easy to pack flat for eventing, easy to re-shape if pillaged on by a drunk pirate.
Don't forget to order some plumes to accent this distinguished head gear (not included).  There's a sewn in pocket to slide them in.
