It can be anything? I would love a mage type skin. Or something like tuxedo skin with 3D glasses. It can have shades.
If you want to make a skin download Paint.net from Paint.net(Lolz). I tried but my Minecraft crashed.
Also the skin HAS TO WORK WITH FAITHFUL 32x32 texture pack.
Junk Jaaaaaaaaaaaaaaaaaaaack X.
Nothin' can stop me playin' Junk Jack.
