The clothing of the working Buckaroo is much different then what you see in most Western movies. (Except for the very accurate Tom Selleck movies, because he makes it a point to get it right).
It is also different then other regions, the Texas cowboy is more about function then craftsmanship. The Buckaroo likes style, function and craftsmanship. Everything a Buckaroo wears has multiple purposes and still incorporate style and usually a bit of flash.
The hat: The hat of a Buckaroo is usually flat brimmed and flat topped. This is for more coverage from the elements. The hat is usually turned up in the back to cast rain in one direction. Most Buckaroos have two hats, a white one for summer and a black one for winter. They are made of fur felt, which is a blend of beaver and other fur into a tight fiber. Felt is the perfect material because of its strength and comfort, not to hot in the summer and plenty warm in the winter. These flat brimmed hats make Buckaroos easy to spot and recognize.
The Wild rag: The wild rag is a neckerchief made of silk. Silk is used because its durable, comfortable and looks good. These rags can be worn in two ways. The first way is like a loosely fitting tie, with the body of the rag draped over your back. The second way is how I have it in the picture, you place the body of the rag in front, bring it around your neck and tie a square knot in the front. This is the style preferred by most Buckaroos.
Wranglers or Levis: This has been the long debate between Buckaroos. Some swear by their Wranglers and other their Levis, and then there is the select weirdos who wear Dickies. There is no winning this debate, but for the record Wranglers are the only way to go.
