It’s warm in Hawai’i. It gets warm at home in the northeast too. But the Hawai’ians, to all appearances, are smarter. “Formal wear” in Hawai’i can be an Aloha shirt. In most of the rest of the country, “formal wear” includes a shirt too, but also another, thicker layer on top of that, and for the men, a fabric noose called a necktie.
