I had a party to attend for my best friends 3 year old son. The theme was superhero's. so of course I decided to go as Wonder Woman! I have to say my little costume was a big hit. After reading all the reviews, I decided to play it safe and go with the extra large. but in reality, I really could of pulled of a medium. I ordered the DC Comics Wonder Woman Cuffs to finish off the look, and it all went together perfectly.
