About FBI Costumes

FBI costumes lean on dark suits and simple windbreakers with bold lettering, Spencer Reid's understated Criminal Minds professor-agent look, Raymond Reddington's far more theatrical Blacklist styling, Burt Macklin's Parks and Recreation parody of the whole genre. Most of it is deliberately plain, except when it's deliberately not.

An FBI-lettered windbreaker is the single fastest way to sell this, cheap, instantly recognizable, and it works over almost any dark outfit underneath.

FBI Costumes: FAQ

No, Burt Macklin is a comedic parody of the genre, worth keeping in mind if you want a lighter take.

An FBI-lettered windbreaker, it's cheap and does most of the identifying work on its own.

Raymond Reddington, his tailoring is far more elevated than the standard FBI-agent look.
