Straw Cowboy Hats

One about that size, but the color and shape of one like this:

So, basically, large and circular with a rounded top, rather than the dented cowboy-esque look.

I’m been looking for one for a few days, but haven’t been having much luck, so I’m assuming people here, obviously, might have a little more knowledge than I do about finding clothes like this, of course.

Thanks in advance to anybody who can help, even in a small way~
