Aha! Yep, I saw you. ^^ If it helps any, I had a guitar but got asked why it was the wrong color and wasn't a REAL left-handed exact same one like Haruko's . . . (cause I can't afford it and I can't play guitar! ;_
Or where the Vespa was . . . lol. It's easy to be nitpicky about a costume you didn't make, right? lol. You looked fine, you can always add the accessories for the next con.
