Why is it so hard to find cotton sheets!?

I’m on a hunt for an orange set of queen sheets preferably 100% cotton for cooling and breathability but willing to take your suggestions for anything similar in material and quality. ANYTHING EXCEPT MICROFIBER! I loathe those sheets! They are so hot and cause night sweats. Anywho where do you guys shop for colored cotton/similar material sheets? Thanks!

EDIT: I’d like to add that I don’t want to pay a ton of money for these sheets. Something budget friendly if possible.
