Nezumi dresses like the great Hyuuga Neji not because he rejects the Branch Family traditional robes, but because he wants to show that he has some power, and will use it to defend the clan with all his might. His arms and hands are bandaged to give them some support- the tenketsu strikes of the Gentle Fist taijutsu can put a strain on his fingers and joints. The only thing standing out from the typical black and white Hyuuga attire is his dignified purple hitai-ate, signifying his outstanding loyalty to Konoha in addition to his clan loyalty. He does not wear a kunai holster because he does not use weapons.
