Online Anime Dress Up Game like "HANAMI"
If you'd rather not spend the time and money making an anime costume or you simply don't have anyone else with whom to play a dress up game, you can play an online anime dress up game. "HANAMI" features a girl with anime-style eyes against a Tokyo backdrop. She has a plethora of Japanese and anime fashions from which to choose, such as a cat-eared hood and Lolita-style lacy blouse. The advantage of playing an online anime dress up game is that you can play for as long or short as you'd like. When you need a short break to unwind, try dressing up an anime-style digital figure.
Anime Masquerade Game
If you've ever been to an anime convention, you may be familiar with the masquerade show in which cosplayers dress up as characters and either reenact a scene from an anime or, more often, make up a completely original skit featuring characters from multiple animes. When playing this anime dress up game with others, you have the option of asking everyone to dress as certain characters from an anime series and reenacting a favorite scene, or asking players to surprise you with their costumes. Then, once you know who everyone is cosplaying as, you can create a short skit of your characters interacting. Everyone should remain in character.
Stay in Character in Public Game
Another anime dress up game you can play with other adults is the "stay in character in public" game. Instruct players to arrive to your gathering in cosplay. Decide on a public place to engage in an activity, such as a park, mall or zoo. Avoid places that require quiet or silence (such as a cinema, museum or library), because players must interact with the public. Make a game of seeing who can interact with strangers in character without messing up. The last one still in character wins. You should be respectful of other people, however, and avoid harassing them.
Drawing Anime Dress Up Game
Another group activity that doesn't require you to cosplay yourself is a drawing game. Draw or print out the template of an anime-style boy and girl wearing swimsuits. Make enough copies of these drawings to distribute to your guests. Hold a contest in which the guests use colored pencils or markers to draw original anime-style costumes and have everyone vote on the winning costume. Or you can ask them to recreate certain costumes from an existing series from memory and determine who most accurately depicts the selected costume.
