I don't think that it would be a bad thing at all! Have you interacted with this sorority before? Make sure you get along with the girls too and don't just like the sorority in general. I'm interested in a lot of sororities' history, philanthropy, etc, but I wouldn't favor a certain group based on that alone.

But anyway, if I met a PNM who already knew about our values, philanthropy, and everything, I would personally be pretty impressed with them. I think you should mention something to them about how you looked into them by finding about their values and such and that you really liked them. I don't think it would go against them or seem weird at all.

Sororities do look at how a person presents themselves with their appearance. Not in the sense that you have to look like a supermodel, but that you look nice & presentable. For a COB, the outfit you described would be just fine.
