This past weekend, EJ went to a friend's birthday party with a mythical theme. They were asked to dress up as a princess or a mythical animal or a fairy or a superhero. EJ chose Wonder Woman and I worked to do a Wonder Woman outfit that was easy to play and get crazy in (and also used very little of my money to purchase).
The most essential purchase for a Wonder Woman costume is the wrist cuffs (at least in EJ's eyes) and I found them along with this awesome felt crown from Shoppe 3130. We already owned the cape and EJ had the perfect shorts but she needed a red tank top. However, the only red item in the girls' department was a thick polo shirt. So we headed to the boys' department and bought a cheap t-shirt that I refashioned into a tank using this tutorial. It worked really well but I also saw this tutorial that I thought would be helpful if I attempt making a tank again.
The costume was the perfect party play-wear and now she can be Wonder Woman whenever she wishes!
