If your teacher doesn't already have a troupe of her students, organize one yourself. Your teacher might not have time to organize and lead a troupe, but she may be willing to help you by providing choreography and suggestions. You and your classmates can share the responsibility for hosting rehearsals at your homes, setting up places to perform, making the cassette tapes with the songs all in the right order, etc. These can be very rewarding because audiences are usually delighted to have you, and they show it. Older women often love to see the glittery fabrics up close, and feel them between their fingers.
Children frequently find the strange music and bright costumes to be fascinating.
Most communities have some kind of annual festival that showcases local amateur talent, and this could be a good place for your troupe to appear. County fairs are another possibility. In these shows, try to have some group performances that are choreographed, and some solo appearances by individual group members. Some communities have several belly dance teachers, some of whom organize events for everyone. Try to perform as a group or as a soloist at each such event, if possible.
