Could never get away with a hat like that, nor a panama. Just not worn by anyone over here. I'd feel too self-conscious. Remember by grandfather's generation had no issues with brimmed hats. But they're well gone now.
This I do wear and has been by good-to-go throughout the summer so far:

Most people, even crazy bald heads, I see without hats even on sunny days. Not a good move for your skin health.
