Typically, a uniform either serves as an indication that the wearer belongs to a privileged class, for example, the military or priestly, or indicates a person responsible for a certain field of activity (the uniform of railway workers, for example).
By definition, people of a criminal nature - the mafia, criminals, assassins, etc. - cannot have uniforms. If they went to serve the state, then they are no longer murderers, but soldiers. But even government spies or agents cannot have a uniform in principle.
The creators simply did not have any imagination for the name of this armor set, or they simply treated it carelessly.
