How do NPC/IFC differ from NPHC on the subject of "Perps"?

Personal experience with a perp... I was in college, went bowling with my boyfriend in the nearest larger town. Saw a girl, about the age of 16 there, wearing an IDENTICAL black hoodie pullover windbreaker with Theta letters on it. Now, people who are familiar with Theta know that we do not allow anyone other than initiated sisters to wear our letters, because they do not know/understand/appreciate the meaning of them. We don't even allow our letters to go on all-greek t-shirts (for recruitment, greek week, joint parties, etc), it just says "Theta."

So approached the girl, friendly, and I assume her mom or sister is a Theta (I've heard from a few people that immediate female family members can wear our letters, I dont know if this is true or not, AzTheta would know). I show her my jacket, and we laugh at having the same one. So I ask "Which Theta chapter do you belong to?" She says, "Oh, I don't, I'm in high school." (I knew this). So then I said "Oh so do you have a sister or is your mom a Theta?" She replies, "No, I found this jacket in a lost and found at the mall. I thought it looked cute."

I was livid, because my Theta chapter was the only one in the area, which meant that jacket likely belonged to one of my sisters.

I paid the girl $10 for the jacket. She gave it to me. I never found the owner though, no one claimed it. Could have belonged to a senior who had graduated the year before.

So personally, I loath Perps.
