Despite your kind words, today I looked at the model and I'm just not digging the skirt. I tried to come up with my own thing but I have to admit I'm not the most creative person.
So I modeled a new one today that was heavily inspired from the skirt of another certain superheroine. ;P

On the other hand I'm quite satisfied with the top.
I also added the boots and arm guards to finish the costume.
I also put some folds around the nipples so it looks more like they are stretching the cloth.
I hope you guys like the redesign of the skirt. I guess it's time to start with the set. :D
