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. If your community doesn't have any such events, check into whether the belly dancing teachers in neighboring communities have anything like that. Organize a party. Invite attendees to bring potluck snacks and drinks to share. Invite each of the belly dance teachers in your community to perform, and take the opportunity to perform yourself.
