Why is the default dress for 007 a suit?
Adapt to the camouflage of social clothes. Suit agents can go to many venues without any restrictions. They can easily go to political places to participate in social activities, or they can pretend to be working parties to go to places where no one cares. The biggest advantage of this kind of agents is that if they deal with multiple enemies, they can attract each other to the swamp. With the complex background color and terrain, agents can easily annihilate them without their attention.
