J ONATHON ACOSTA wore a blazer with a guayabera, a traditional formal shirt in the Caribbean, on his first day as a senator in Rhode Island’s legislature. Since then he has worn informal attire, a better reflection, he says, of his mainly Latino constituents. He often wears knitted hats and cardigans. The only wardrobe rule said that people must be “properly dressed”. That changed on March 23rd, when the chamber passed a new dress code stipulating “proper and appropriate attire”, such as blouses and collared shirts with a jacket.
