Yes, this plan is reasonable. Dance schools should not only consider students' wearing comfort in indoor environment, but also consider guiding students to form elegant wearing styles. Moreover, different dress requirements are provided according to different dates and types of activities, which can also ensure that students make the most appropriate dress choices according to different situations. In addition, it is also important to ask students not to roll up their sleeves, because it is not in line with etiquette and is not conducive to boys to shape the image of a little gentleman.
