I'm getting the impression that Senjumaru's grand contribution to Soul Society was the shihakushou. We often take it for granted as merely being a Shinigami uniform, but I wouldn't be surprised if it has some subtle special properties that will end up being pointed out to us.

Also, judging by what happened with Bambietta, I'm waiting for the wave of edits calling Karin "well-endowed."
