Terrible Disguise

''Guy, I know that's you. You're clearly wearing nothing out of the ordinary other than a mustache. I'm not stupid, stop thinking of me as such.''

When someone has a disguise that barely alters their appearance, they have a Terrible Disguise. This may fool Figuratively Blind People, but it has absolutely no effect on the audience. Speaking of the audience, the character's disguise might be so awful so then we know who the disguised person is. The most common Terrible Disguise is a mustache.
