WHETHER or not it was inspired by Michelle Pfeiffer's Catwoman costume in Batman Returns, the Thinning Belt brings a new dimension to bondage wear. Made from black neoprene (the rubber used to make divers' suits), it is designed to be worn under clothes and is intended for medicinal rather than kinky purposes. 'The idea,' says Tanya Morgan, its sales director, 'is that you get slightly, er, moist, not sweaty, and lose weight.' Ms Morgan claims to have shed one and a half inches from her waistline in one day, 'though it doesn't necessarily stay off'.
