A dress code has both practical and aesthetic purposes. The study of dance is a physical discipline that requires teacher supervision.  Proper attire in dance class enables the teacher to give corrections regarding body alignment and insures the safety of the dance.  Hair must be kept off the neck and pulled back from the face.  For females, buns are required in all ballet classes. Jewelry is not allowed in class and should be left at home. Any student who does not have proper attire may be asked to observe rather than participate in class.
