I'd say turn her down. Sounds like you've already made up your mind

You haven't said anything positive about her so it's looks pretty clear that the negatives are meaningful to you.
You should ask for advice on that in the Manshion thread instead, I think :S Personally, I don't like the dull color. I prefer flashier stuff with brighter and stronger colors. Maybe with prints on them as well. Like you said, you look decent-looking, which you made sound like a bad thing, so it probably is, is my line of thinking

And don't fold your arms. It looks defensive in any situation (man, I really need to listen to my own advice...)
