A Serious Matter

Katie and I bought our tickets for the midnight showing of the Harry Potter 7 movie last night. Because she can't ever pass up an opportunity to dress up, it has been decided that we MUST attend in costume. I said the typical, "Lets put on a cape idea" but she vetoed that, wanting something a little more extreme. Our two idea so far are...

1. Gobblins...
2. Her on my shoulders with her looking like Hagrid...

Obviously we're in a desperate need for better suggestions.

All ideas are welcome!
