We thought we’d seen the male underwear for everything; the front enhancing, the bum lifting and of course the male Spanx, where it all gets sucked in, but yet another type has reared its head - the bum enlarger or shaper. It works by having two padded inserts in the back of the underwear to give you the perfect 'bubble butt' shape. Like shoulder pads for the backside, they sit to the sides of your behind giving your arse a more rounded and fuller shape.
Called ‘Active Shape’ underwear by American brand Andrew Christian, the pants have invisible rear padding which is removable at your preference and adds 2 inches onto your buttock measurement. A male J-Lo, Beyonce or Rhianna, it looks completely natural with no lines or bumps.
TheChicGeek's Verdict - Surprisingly comfortable, you forget about

the addition and don’t feel conscious unlike others of these altering pants. It works best in lightweight trousers such as chinos as jeans kind of do this job anyway. The shape is good and looks like you've spent weeks in the gym doing squats or something. Expect other brands and retailers to copy this idea.
