Shako

A shako or shacko (, , or ) is a tall, cylindrical military cap, usually with a peak, and sometimes tapered at the top. It is usually adorned with an ornamental plate or badge on the front, metallic or otherwise; and often has a feather, hackle, or pompom attached at the top. Extensively used as an item of military headgear during the nineteenth and early twentieth centuries, the shako now survives as part of some ceremonial uniforms.
