About Agent Costumes

Agent costumes lean on sharp, functional clothing, Jack Ryan's understated professionalism, Lana Kane's tactical-chic confidence, the Men in Black's iconic suits. These characters dress to move fast and blend in, not to stand out.

One subtle gadget or earpiece-style prop adds detail without overdoing it. Keep the rest of the outfit clean and simple, that's what actually sells the professional read.
