Finding an authentic Wonder Woman costume is apparently a much more difficult task than one would expect.  I settled on this one, but had the make a few modifications:
- Tiara & bracers - They're cheesy, they're stupid looking, but I wore them anyway for lack of a better option.  If I had a bigger budget for this costume I would have bought Elope's tiara and bracers which are actually made of metal.
- Cape - WW never wore a cape, so this got thrown in my bag and only pulled out at 1am when I was freezing cold.  Within 2 minutes of putting it on, someone pointed at me & said, "Look! It's Supergirl!"  Sigh.
- Corset - The corset is good as-is and is the most sturdy part of this costume.
- Skirt - Again, sorry kids, but WW did not wear a skirt.  The color and pattern of this skirt are right though, so that ranked it better than the WW underpants that I had as a backup.  In order to get a more authentic look, I sewed the skirt into a pair of bloomers.  However, it's not actually big enough (or perhaps my backside is too big) to cover everything, so I had to sew it TO a pair of underpants so that my crotch wasn't open to the cold Halloween wind.  It ended up looking great from the front and the back, but if I had walked up a staircase, my fraudulent bloomers would have been revealed.
- Tights - Really? No, thank you.  I opted for the Rubie's officially licensed WW boots instead.
