And if you need Kiss make-up ideas you can find a lot of them too. You can check out The Demon makeup stencil and The Starchild makeup stencil and watch how Gene Simmons puts on his black and white make-up.
If you prefer some other Kiss members like The Starchild (Paul Stankey), The Spaceman (Ace Frehley, Tommy Thayer), Catman (Peter Criss, Eric Singer), The Fox (Eric Carr) or The Ankh Warrior (Vinnie Vincent) you can find many costumes with their characters too.
And make sure that you put on their make-up and that's actually the most inexpensive Halloween costume. Just some make-up and black shirt, and everybody will know which costume are you wearing.
And you are ready to party.
