Because it is a party, it is recommended to wear sequins or clothes with better lighting effects. What is said upstairs is ok, with the lady above and the skirt below. It must be beautiful. Many stage costumes can be worn. Dresses suitable for middle school students are also possible, because it is a special party. This is both a school celebration and an art festival. So, you can go to the stage clothing store to see if there is a suitable one, or you can listen to the teacher's opinion, and then it's OK.
