(which is why we have BYU gear count posts).
It's one thing to buy one royal shirt and maybe a jacket and wear it to the "royal-out" game.
It's another thing to own 10 tees, 4 polos, 3 hoodies, and a jacket, and mix it up all the time.
The bookstore would have the stats and I'm pretty sure they'd be against going to Royal "full-time".
I kind of like mixing it up. White-outs and Black-outs are more annoying for me. I'm fine with just Royal/Navy for football, white-outs seem to work well in the Marriot for Basketball.
