I would also charge the same amount for all kids costumes. The cost of costumes vary by companies and styles, etc. You need to add $ to your cost to cover shipping and the need to ship back for possible exchanges. The costume companies will charge you extra for exchanges and most of the companies will not take back costumes, in case you have a parent who "changes their mind". I have been stuck with several costumes when I wasn't experienced enough to get the costume fee in full before I ordered.

This is a great web site and you'll love all the help.
