User blog comment:Boss335GT/Episode 9 / 10 inconsistency + poll/@comment-25160154-20131105035357

As the main guy for inconsistencies I've already dissmissed this. They don't fight in their uniform, only thair combat gear (as monty calls it) So there was a short time skip in which Weiss must change to her standard outfit.

So in short, no it's not an inconsistancy.
