Alot depends on the weather. I usually am in jeans and t-/sweat shirt. It will probably be warm where you're at, right?
Nothing special, unless you're trying to make a statement:). Cowboy hats, chaps, long sleeve western shirts, neckerchief's, etc. I was surprised at first how many people dress the part. I'd rather go for comfort.

Well I'm comfortable riding in sweatpants and a loose T shirt but that might be too casual.
