FBI agents' dress code varies according to their job profile, taking into account local conditions, traditions, and demands.

They typically wear suits 5% of the time. If the agents must be present on court grounds, they will generally get dressed in a suit. Executives at the FBI are typically dressed in suits, but exceptions do arise.

Street agents dress in everyday clothing to blend in with the general public. In any case, officers investigating white-collar offenses usually dress professionally.

While agents overseeing cybercrime and counter-intelligence appear in business casual clothing. Agents assigned to gangs and drug-related enterprises dress more informally, generally in jeans and T-shirts.
