Any one else notice that shes wearing Ichigo's Shinigami uniform?

IN YOUR ENDO!

not really. Because the shinigami uniform is practically the same. rather.. they are ALL the same.. I suppose she is just wearing it *like* ichigo.

And besides. the only time when Ichigo has a way different shinigami set of clothing is in his bankai. where the inside of the robes have a red colour to it XD.

Ichigo's uniform would be way too big for Rukia. He's full foot taller than she is.
