My question is, what does a cowboy hat do? If it’s just to keep the sun out of your eyes, and the rain off your head so it runs down your back, then go for it. It’s clearly not to keep your ears warm. I looked up why cowboys wear cowboy hats and apparently it also keeps your head warm. But, I agree with your female friends, it does look kinda cool. And I wouldn’t worry about posing. Not everyone who wears yoga pants does yoga.
