I will wear my dirty jeans, shirt and boots but I usually swap a cowboy hat for a ball cap and leave my spurs in the truck or at home if I need to run to town.
Going into another persons home I will always remove my hat and my spurs, not doing so is bad etiquette.
I have to say a friend of my husbands recently moved to TX from up here and he was thoroughly disgusted when he seen something at a little hamburger stand.
Apparently a "team roper", I put that in quotes as an indication of a wished-he-was, was eating a hamburger with his roping glove on. I think that is taking it way too far- you can't be bothered to pull a cotton string glove off your hand before you eat?
ETA: the last paragraph was not an indication of TX horse folk, just he has been absolutely mystified about how things are down there as whole and that was the latest...lol! Poor Yank.... ;)
