Cosplay is great!

Cosplay is short for “costume play”, which means play-acting in costumes. People who take part in cosplay are called cosplayers. They usually create or make costumes of their favorite animation characters by themselves or get a tailor to make them. Sometimes they even prepare small things, like knives and earrings, which the characters wear or use in the animation.

Cosplayers are creative and proud of their work. They spend a lot of money and energy on it. They not only dress up as their favorite characters in the animation, but also act like the characters.

New trend (趋势) is on!

While Chinese fans are busy cosplaying characters in Japanese animations or movies, Japan, as a big country of cosplay, now has a trend to cosplay non-Japanese movie characters. Japanese cosplayers like the characters in Star Wars and Lord of the Rings very much. But the most popular ones are from the Harry Potter films. They have a very large number of fans in Japan. The character who is liked the best by Japanese cosplayers in Harry Potter films is Draco Malfoy, though he is Harry’s rival(对手) and always tries to get Harry and his friends into trouble.

Cosplay doesn’t have anything to do with age. Whether you are 5 or 50 years old, you can be a cosplayer if you are creative enough!
