Didn't follow the comics, bit I watched the tv series when I was little, then got the dvds when they came out. I thought that the idea was, that she was hundreds (possibly a thousand?) years old, and that the women who lived on her island were the same.
The first series which I think was based more on the comic than the others was set during I think it was WW1? (that's World War, not Wonderwoman 1!). Her costume was a mixture ancient defensive jewellry (the tiara, the braclets and the lasso of truth) and the rest of the outfit made up of garmets that looked like the American flag (probably to distract Americans from the fact that the red star on the tiara looked suspiciously Soviet and also prevent "friendly fire"! )  ;)
The first series was the best, then came the Deirdre Barlow specs in the second, and the annoying little gold robot in the third. Some characters work best when you don't modernise them.
As someone already mentioned, the new costume looks like Rogue, and I think it looks a bit like Jubilee from the cartoon. Marvel wouldn't be too happy.
She's supposed to be Wonder Woman a DC Comics classic, not "Biker Chick from Marvel" and she seems to have ditched the flag, probably trying to appeal to a more international audience?
Keep her the way she was!

Next up! Captain America ditches costume for a Hawiian shirt, Detroit Tigers baseball cap and a moustache. Look out Magnum!
