I now know that Mattel already has several Wonder Woman Barbie dolls. See [http://www.barbiecollector.com//images/showcase/products/24638_9993_main.jpg 1999], 2005, and soon to come Oct. 2008. But who wants to pay for collector's items or wait until October? That doesn't feel right if you're a DIY-er, anyway. Besides, I see things I'd want to change in each of those boxed Wonder Women.
At any rate, this is a good chance to try some Barbie modification.
Step 1: Here she comes... Miss Imitation Wonder Woman
In the end, I found several Barbies that could fit the bill, each with different strengths, so I decided to make the most of each contestant in the 2008 Imitation Wonder Woman Pageant.
Ballerina Barbie Pros: opposable limbs, blue eyes, "diamond" earrings. Cons: blond hair
Casual Dog-walker? Barbie Pros: narrower blue eyes. Cons: blond hair
School Teacher Barbie Pros: dark hair, red lips. Cons: brown eyes, molded with one bent arm and one straight arm, tan skin tone.
