The main problem is that I don’t have any interesting clothes, and this is at the last minute. My wardrobe consists of jeans and t-shirts, with a few normal-looking skirts and dresses. I think I’m going to have to be lame about it and wear boring clothes: If you don’t like me in my normal clothes, then you’re not worth being my friend!
Alternately, I could wear a sign that says: “would you still be my friend, even though I don’t own any interesting clothes?”
But please, keep posting ideas! Maybe something will jump out at me that I can pull off at the last minute.
