metal wire frame for forming, velcro to hold corners in place.  In all a good costume hat.  Red 1" material sewn into the band of the hat, visible all around the hat, plus 1 side 18" x 2 pieces hang down.  Great for pirate look, not as good as I was hoping for renaissance look.  tried to pull the red material out, but it looked like it would damage the seam and the hat, so I left it.
