It's not about creating art based on anime that they have a problem with, it's the creation of copyrighted material for re-sale that they have problems with. You see if you make a copy of the Sailor Moon suit and sell it you get the proffit and not Bandai, but 99% of the reason your product sells is because it is Sailor Moon. So therefore you are making money from them. It is the same for all copyrighted material. If you keep it free and state clearly who owns the copyright you will be ok. You make money off it, it's another story. Plus also the brand has an image too, if for example you started selling Tellie Tubbies along with strap on dildoes and a 101 swedish pump action sex poses to go with them, you then not only proffit from the brand name but you also destroy it's reputation as a kindergarden childrens TV show. and when the angry parents complain about it they go to the makers of Teletubbies, as they will mostly think it has come from them on some level or another. So there is a good reason we have these laws in place.
