My old studio was never strict about these things. Girls came in all the time with their hair down and in skinny jeans. When we were supposed to wear black leggings for competition, some girls would come to competition in black skinny jeans because It looks just the sameI think studios should be strict about it. Come to class in stretchy clothing (hot pants, tights, jazz pants, yoga pants, etc) and have your hair up. For safety reasons. My new studio requires that every dancer wear hot pants, tights, dance shoes, and a tank top or a leotard, tights, and dance shoes. We also have to have our hair in a bun for ballet. For lyrical and jazz they let us put our hair down but we still have to have the right clothing and shoes. Even if we just have socks, we fold them into the shape of a dance paw
