I don't support any of the waifish choices that get thrown around either, like Natalie Portman, Summer Glau, Sarah Michelle Gellar, etc, but I do think Wonder Woman has to be attractive. I remember her being described as one of the most beautiful women around. Ideally, she should look like she could beat up an army of klingons AND walk down a runway at a fashion show. It doesn't have to be one or the other. And being strong and capable doesn't mean looking like a man-ish wrestler.
What would a live-action Wonder Woman look like to me? Maybe someone like Lisa Snowdon.
And maybe Natalie Glebova. I made an avatar featuring her as Wonder Woman a while back...
It's hard to find anyone who could top Lynda Carter though.
As for the costume, I say leave it. Putting her in armor smacks of trying too hard to be "realistic". An amazon woman from another world not dressing like we think she should is realistic anyway.
