American costume

In 2009 Halloween day, I went to the kara-ok , after I rode a bus to go home at 6 or 7 'o' clock. I saw a lot of people who wore a funny costume in the bus. There were many kinds of costume. At that time I saw some funny costume, which was batmen costume. This costume was so cute. This costume's point is when someone lift their arm with this costume, the batmen wings are appear in their inside arm. ha ha.. ,and I saw some scary costume, which wear a mask and lift a sword in their hand. If some Asian who don't know about the Halloween day, this costume will be scared this kind of person. I have no chance to wear a Halloween costume in 2009. If I have chance to wear a costume, I want to try a scooby-doo costume. I hope next Halloween day will be fun.. not like 2009 Halloween day. T T
