I was really pleased with my Hollywood Tower Hotel bellhop costume. It turned out really cute! I ended up not wearing the hat - I just couldn't figure out how to get it to stay on my head. But even without the hat, I really liked it! It was wicking, so it was functional as well. I got lots of complements on it!
I even managed (peripherally) to make the runDisney Facebook race photo album! That's me right behind Thor! He had quite an intense costume, full pants and sleeves in all. He even ran the entire thing with that hammer - not sure how he did that.
