Male or Female?  Observe what your child is into, what they watch and play with and who is there favorite charater.  I make costumes from toy figurenes or books but i have to have something to work with, i have made costumes for children just to see them happy and having fun. I try to be true to the charater and are hand made.  if you have a hint on this above ? my costumes always win in contest. my email is j2tdoe@gmail.com  I am currently making the three ballerina's in the wizard of oz/ couple of disney charaters.
