Wearing letters in colors other than your GLO's

[REE1993]

I know I have seen this topic before, but I cannot find what I need via the search feature.

I keep reading about wearing ONLY your GLO's colors when it comes to letters, but back in my day, we used to get shirts/sweatshirts of any color with cute fabric for the letters themselves.

Is there a new trend in not allowing or discouraging members from wearing letters in colors that may belong to another group? For example, I have an old yellow sweatshirt with red and green plaid twill letters. I know that at least one sorority has these official colors. So would that be disrespectful?

I have seen sisters (NPC and non-NPC) wearing different combos of colors and patterns. FOR EXAMPLE: Is is inappropriate for an AXiD to wear a pink sweatshirt patterned fabric letters of, let's say, pink and white hearts (Phi Mu has pink and white)? I mean, it would be cute, but is it inappropriate now? Greekwear sites still offer patterns.

I am not speaking of chapter jerseys (which they didn't do in my era), I am talking about letters we buy each other or ourselves.

What's the scoop here?
