Yes, that's right. There are actually items of clothing that require batteries. We're not talking about the new-fangled camping and survival clothing that uses batteries to generate heat. We're talking about those holiday sweaters and sweatshirts that light up.
In fact, on a popular home shopping network, you can buy a Christmas sweater festooned with a fiber optic light-up Christmas tree powered by two batteries "conveniently hidden in an inside pocket." Does that sound like the perfect item of clothing for an ugly holiday sweater party, or what?
