So you've got your underwear and your bra, and a few flimsy things for more specific occasions, but that's about all the underwear a girl will ever need, right? So wrong, friends. Apparently your cleavage—well attended to by the eyes of the opposite sex, but undeserved by the undergarment industry—needs clothing too. According to La Decollette, makers of an overnight bra for your cleavage, a proper lady should never go to bed without one of their garments, lest she fall victim to the plague of cleavage and neck wrinkles. Combined with moisturizing cream, this bib with straps is said to prevent signs of aging and keep you taut long into your winter years. The only downside? We have a feeling you'll have more than one person asking why your racerback tank is on backwards. (The Frisky)
