The Jabbawockeez Contest

The Jabbawockeez Contest is basically a two month (8 week) camp where you compete in dance competitions.
The first week no one wears their mask unless it's the Jabbawockeez showing you a routine. However, once the second week starts everyone wears a mask whenever they are in each others presence. Everyone has a uniform for each day and no one knows who is who. This is to make it fair when the Jabbawockeez judge. At the end of each weak every dancer will perform a solo dance and of course a group dance. The only thing that you can use to tell each other apart will be the color of your mask. Every dancer will have a different one.
The contest will include four girls and four guys. Though you think it will be easy to tell the difference between them, everyone's outfit matches - everyday. All clothing will be extremely baggy so as not to give away any bodily features. Even during dance practice you are required to tie up your hair and wear your mask.
