Outfit Reputation Confusion, Help!

[Honeycone]

Hi!

I'm very confused how the outfit / reputation system works. According to this wiki (link below), you can kill enemies whilst disguised and not suffer any reputation changes as a result. What I've tried doing is putting on a powder ganger uniform (and the game tells me I'm dressed as a powder ganger), killing some caesar legion forces. However, even if I take off the outfit afterwards, I'm still hated by Caesar.

So... Am I doing something wrong? Can I kill faction members whilst outfitted and not suffer any reputation changes to my character?

Thanks.

Judging from experience in my own game (where I went a long stretch wearing the same bit of NCR armor) --

* Wearing faction armor resets your visible reputation to something appropriate for that faction.
* Actions taken while wearing faction armor DO affect your 'real' non-disguised reputation.
* Your non-disguised reputation will be used when you switch back to non-faction armor.

e.g. I did a lot of quests for the NCR while wearing NCR armor; I ended up being only Accepted while wearing that armor, but Idolized when wearing non-faction armor. There were situations where when I needed something from an NCR officer whom I'd personally been doing quests for, I would get a positive response only after removing the NCR armor even though I had been wearing the same armor for all previous interactions with him.

This also affects whether factions attempt to hunt you down (Legion vilification + no faction armor = assassin squads; Legion vilification + faction armor, even *NCR* armor = no assassin squads).

I read very closely and it seems that I can freely kill a faction if I'm disguised as an enemy to my target. I have yet to try it though!
