How common is it for American men under 40 to wear collared button-up shirts if they are not going to work or formal occasions?

I see a lot of European men under 40 wearing collared button-up shirts all the time even if they are not going to work or formal occasions.

I used to have a European friend who wore a blue collared button-up shirt with short sleeves to the beach at that time he was in his late 20s.
