Okay so the shirt is a lot smaller than it looks, I'd say it's a smaller size 4. I got in my freshman year of college ('03-'04) and only wore it a handful of times, mostly to chapter. I have a picture of a much younger, smaller me wearing it somewhere, I'll have to dig it out. I'm looking for $40 shipped.
I can't find the actual camera right now (hence my using the computer camera), but when I do I can post another pic so you can get a better idea of the colors. It really is adorable.
