When Marilyn Monroe stepped over that subway grate in The Seven Year Itch, her derriere flash lent a paragon reaction for that blustery subway experience most women who have worn skirts have experienced, though we wish we (and our backends) looked as glamorous when we catch our summer dresses up around our eyebrows. To help ensure that we put our best butts forward, Protec-Style Lingerie is releasing a Marilyn panty, made from an ultrathin fabric that is stain-resistant, anti-fungal, anti-viral, and a bunch more anti-wtf-are-they-doing-down-there things that will protect your business from the malefactions of any fast-passing subway car . The panty retails at $21 and will be available at Protecstylelingerie.com. (WWD)
