I apologize if the answer was supposed to be obvious, but I didn't see anything on the topic and I am curious.
The winter bash hats are pretty neat and there's lots of different ones. Is there a way to display more than one at a time? I suppose too many would hide the icon, but a few might work quite well. It looks like they're just layered on top of the icon picture, and I don't know if it would cause problems to have more than one layer at a time, or if there might be a different way of adding many hats.
I would be pleased with either a way make it work, or a reason why it doesn't (or shouldn't).
