i guess we all agree that the right haircut and -color can hugely influence the perfect look of a costume. to name two examples, lex luther with hair is just a guy wearing a suit (the real look would be a bald guy wearing a suit, but that's another story), and a blonde wonderwoman would be like having sex with your cousin, it looks okay, but you know it's wrong
but to get to my question, what really interests me is what do you do with your hair (facial hair included), and where does your love for a perfect costume end? do you prefer to grow your hair and/or dye it, or do you just wear a wig? or don't you do anything and let your hair as it is though it means that your look isn't 100% accurate?
i come up with this question because of two costumes i wore during carnival. one year the topic was "Rock'n'Roll", and i had some Elvis-like sideburns, another year the topic was "Christmas" and i had a full beard colored white, and for both i had to grow my beard for several weeks and months. back then i could do that, as i was a student, but what do people with a job do where they can't run around as they want to?
