Am I misunderstanding how faction armor works? It's my understanding that while you are wearing faction armor, NCR for example and attack another faction, Legion, in this case, I would not gain infamy.
To test that, I donned some NCR armor and fought some random Legionares. After a few of them went down, my faction rep turned to hated. I figured that waiting a little while and removing the armor would cause me to not be villified. However, I'm still hated.
When do I get reputation changes while wearing faction armor? I did have Boone with me, do companions affect rep gains as well?
