From Wikipedia: "A top hat, silk hat, cylinder hat, chimney pot hat or stove pipe hat[1] (sometimes also known by the nickname "topper") is a tall, flat-crowned, broad-brimmed hat worn prior to and including the 19th and early 20th centuries. Now, it is usually worn only with morning dress or white tie, in dressage, as servants' or doormen's livery, or as a fashion statement."

First hat is 112 faces or 208 triangles, procedural textures.  Others may have different poly counts, and two have public domain image textures (the playing cards).  There are six hats in total.
