A new study by deadgoodundies.com reveals that men buy more colorful underwear when the economy is booming and wear white, black and grey underwear during downturns. Company rep Jane Garner says, ''The site, which has been collecting data across a five year period from 2007 to the present day, has noted a recent upturn in sales of pants in so-called frivolous colors - a purchase that may be considered a luxury fashion item as opposed to a practical or solely functional item. Believe it or not, over the past few years men’s branded underwear collections have become increasingly colorful, more so than women’s, in fact. Men have a huge choice in terms of plain colors and patterns this season, and I’m not just talking about quirky kiddie prints, which were all the rage a few years ago.''
