If you were to dress as Uncle Seymour Coffins...

…is long hair a must? Or does it not matter that much?
I’ve been contemplating dressing as Uncle Seymour for Halloween this year. I know it’s a ways off, but if I commit on this costume and if I in fact do want long hair, I need to let it keep growing. I don’t want to go with a wig, I’m not really a fan of them. More than likely, no one will know who I’m supposed to be, so in that aspect, it probably wouldn’t matter so much. But, I’m a stickler for screen accuracy and I always want to be as accurate as possible with my costumes. So what it comes down to is that it would be a personal bug-a-boo of mine.
I’d like to hear your opinions, what would you do?
