Thing is, Shelby, not all of us have had the time or desire to create a super-complex costume, or even a basic outfit. It is our own failing and punishment; you don't need to make us suffer more.
And for me, at least, a costume is really just a state of mind, which I have already prepared for myself.
Oh, and if Whippy is adorable and ridiculous enough to be a costume on his own, then I'm going to find an alternate reality where he IS. So there.
