It's very cute! Though for full possibilities, I definitely think everything should be removeable(i.e. stockings/footwear), as well as having a bra for added tension/options.
The player model at the moment is placeholder and will be changed soon. The new model will have a bra and removable footwear. There will also be additional clothes added over the course of development.
I only have plans of having one character. I do plan on having a progression system where she can only remove so much at first, but as she streaks more and more, she can remove more clothes and has more confidence to last longer.
