need an XL or XXL summer hat

Does anybody know of an internet store that sells women's hats in those sizes? Not "one size fits all", not "SM/MD or MD/LG", but actually big? I get headaches from the pressure if sunglasses or hats are too tight.

I would prefer a pretty straw hat and even something colorful, but I have not seen anything in my size even on reputable sites, so by now I am prepared to buy the ugliest non-straw khaki hat, as long as it is not tight and has wide brims.

Not cheap but I bought my hat over ten years ago (the one with the hat band) wash it in cool soapy water by hand, wear it in the pool, it's still fine. Mine is a little big tho, I sized it too generously. I can't usually wear women's hats, even when i was a kid. All those math brains have to fit somewhere!

Also makingitbig website has some cute black or white or black and white hats, but idk about the size.

Wow! This is better than I hoped for - not just big but with SPF, to boot! Now I won't have ANY excuse not to go hiking!

Thanks!

I won't buy those because they are one size fits all, but I will bookmark the site itself as they have gorgeous plus size tunics. Not good for my budget now, but, perhaps, one day.
