I mean what does it do exactly? What capabilities will the uniform grant the one who wears it once you hit two stars then expand it into three? My guy will be using increased speed, maneuverability, and allow him to hit harder and faster at two stars then allow him to use an ability called 'shadow boxing' which lets him preform multiple moves at once. With your given activity I don't know exactly how that would translate into abilities. 

I'll allow history expanding in roleplay due to the nature of your character.
