It took me a while to finally have a preference, and I'm still not sure which one I prefer, but I'll go like this;
1-Pink
The blonde Zelda is still really pretty. She doesnt look like a plastic doll like Peach. I never would have thought this one would fall first for me, but I think it's my favourite one now. This one and the default purple one are both on top for me.
2-Purple
Brunette fits Zelda so well and she looks more serious and powerful that way. I think purple fits her royal status and she looks glamorous with this outfit. It rocks.
3-Green
The green outfit is simply amazing, I love it. It's sexy and impressive. I like how it kept the white dress, unlike the blue and red ones.
4-Black
I think everyone knows the black dress is cool. Personally I like the white hair, it gives her an evil sorceress side. Sheik in black is the coolest design ever made for a video game character.
5-Red
I like the fact that her dress is blood red, it makes her look like a fierce fire witch. Too bad her Sheik counterpart is too much pinkish. I like the red and blue dresses a bit less than the first four.
6-Blue
I think it's a bit dull but I like it nonetheless. Sheik's red bandana leaves me perplexed, but its not about Sheik right now is it? I still like the blue outfit a lot, but less than the first five.
