I want to know if I should buy a blazer for my internship at the FRBNY starting February. Based on what a recruiter told me, the program will be business casual with some business formal situations. I'm aware that business casual generally consists of slacks and a dress shirt - and maybe a semi-formal jacket. I like dressing more formal but I don't want to be out of place. Should I buy a blazer or stick with slacks and a dress shirt?
