According to the designers at vintageskivvies. com, the full, elastic waistband is the worst thing that's ever happened to men's underwear. The company specialty is tie-style boxer shorts with button flies that are modeled after the standard-issue underwear worn by soldiers during World War II -- an homage to a kinder, gentler, less restrictive era of underclothes. And although, technically, the Web-based retailer traffics in panties, don't expect any frou-frou fabrics or floral print: These shorts are 100 percent cotton, and the color scheme ranges from plaid to, well, plaid. Vintageskivvies.com celebrates the classic boxer -- and a brief-free world.
