That dreaded suit and it's component have many meanings or so Lucas will have us think. That chestplate and it's button say that LITERALLY there are machines where his heart once was. That helmet can resemble a skull and it means how Anakin is not really willing to live, because he's not living in peace. Not at all. The cape can mean that as long as he tries to get his past behind him, it will forever be there to haunt him and keep him there. The FAKE legs can be interpreted like Anakin is living in a lie, trying to give his life some sense by fighting something he really should not, but it was the only thing he had left. Like his robot legs to move is the only thing he has. His original flesh being completely hidden from view it means literally that Vader has consumed Anakin. We only see the suit and mask and never his face, until ROTJ. And I think most importantly, the BLACK color. It clearly can mean that he's given up on the compassionate style, that he thinks that nothing can be achieved by democracy. Anyone can find other meanings like these about the other objects in that suitÂ¿?
