Sheet two however shows ideas for more casual clothing.
Final Sidekick figured out; more tentacle-like details added, feet and general form of the body defined.
And few more serious ideas. My favourites are number 3 and 6. I wanted them all to feel like something that doesn't necessary have to cover the whole body but only needs to give the audience that feeling that "whatever will do, because he doesn't want to wear it anyway".
Any feedback will be well appreciated :)
