“Jeans were created for farmers”. Are jewish farmers allowed to wear jeans?
Do Rabbonim wear pajamas to bed (do they go to bed)?
Do yeshiva bachurim go swimming in their hats and jackets?
Do executives wear suits when vacationing with their families in Disneyland?
Do executives all over the world wear suits? When I traveled to Puerto Rico on business I may have been the only peron on the island wearing a suit jacket and tie (with the possible exception of Rav Zarchi, the chabad shliach and local Rav).
I don’t think the “does a ploni wear such attire” argument get you very far because the answer to that question varies based on the time and place.
