Sorry, but I have a major problem with people who wear sweat pants in public. Simply put: sweatpants are only to be worn in two places - at home and at the gym. They aren't intended for public fashion (unless you have to run to Walmart which you'll fit in with every one else in the store).
One company would like to change the rule of "sweats" in public... Betabrand has created "Dress Sweatpants." According to the description on their website, "At first glance, Dress Pant Sweatpants look like fine charcoal wool trousers. Which they are, except for the wool part. Now look closer; better yet, put on a pair. Dress Pant Sweatpants have a relaxed, straight-leg fit. They're not skinny-fitting, but definitely not baggy either."
You HAVE to see the pictures of what these things look like on their site. Better yet, there's even a PHOTO GALLERY of guys wearing these things at work, weddings and parties (?). Something tells me while they may look like wool pants, the minutes your lady puts your hand on them, your slacker secret is up!
