If its based on a bad/cheesy holomovie the outfit might actually be a bit more sexy/provocative than what a Jedi would usually wear. As in the movie the female Jedi might be there for eye candy On the other hand it could be an extremly martial sort of armor. Maybe the movie portrayed Jedi as much more warlike than they actually are? Or maybe its some weird combination of the two? Depends on the series in question I would guess. In a more episodic format like a crime/detective series or even something like Supernatural I think its pretty easy. In something like say Lost it might be harder because that series deliberatly kept many details on both the characters and there backgrounds as well as the island itself in the dark for season after season. I think @GregMcP is right best mention simply how far you've watched as it would prevent confusion if a later season does contradict some of it and also prevents the reader from maybe accidentially spoiling that aspect of it.
