The undershirt, which is made of polyester, spandex and nylon, is designed to force the wearer's body into a leaner form and correct posture under normal clothing.
"It's a very tight-fitting T-shirt, so it's not like we're asking men to wear a bra. It's quite inoffensive," the spokeswoman said. "We've never stocked male control-wear before, so it will be a test. It may be that women will buy them for men, until men become more familiar with it."
The shirts are expected to retail for about $70 each.
