Not much now, I won't know in a few years. You can wear gymnastics clothes during the basic skills exam, and they will give you some time to change clothes when you jump into the theater. Generally, gymnastics clothes are put directly into the costumes of the play. It saves time. If you don't have time to change clothes and take the exam together, you can put a pair of seven-point leggings over your pantyhose, which looks very professional.
