It's very likely, yes. Do you have any costume materials at your disposal? Being an active member of the theatre community, I've always had an abundance on hand. It has always been very convenient to have a base costume set for each child that you can adjust according to their preference once they've made their final decision. Of course, if you're going to be making preparations from scratch, you should start now because any quality costume is going to require a little dedication, especially if you want to make it adaptable to a theme change.
