I wound up going in something comfy. I wore my leggings with above the knee cut jeans, my mary janes and my golden books shirt (which I bought at Hot Topic, but it's been discontinued

).
Of course, after the concert I bought an oversized Beck shirt and threw that on over my other shirt.
The concert was
AMAZING.
If you want to hear about it, I Xangaed it.
