what does Macbeth's appearance (i.e. manner of dress) tell us about him/her?

In the early part of the story, his dress shows us who he is, a great warrior who owes his allegiance to the king. Therefore, he dresses like a warrior. On the night that he kills Duncan, he is dressed in his nightclothes. In his kingly attire, he typically dresses in royal robes, more regal clothes. At the end, when he fights Macduff, he dons his warrior attire again.
