I do like the idea of playing one character but in different outfits/roles.
Like Nadeshiko and Nagihiko from Shugo Chara.
We're very grateful for all the suggestions! <3 We've been looking at some yu-gi-oh card pictures too and found one we quite like. It's the Pikeru and Kuran card. If we adapt the design to a normal person it could be quite the outfit!
Iggy, thanks for the suggestion, but I'm not a newbie at sewing. I am in fact a tailor student.
