Considering the t-shirt under a long-sleeve t-shirt/thermal is the everyday style of many members here (myself included), Details had a little rant about it in their last issue. You can read it here [men.style.com]. I didn't know the look was so "O.C." hah. Edit: This is my favorite sentence in the whole piece: "But it turns out you're really just an unwitting slave to the celebrity-enabled fashion Zeitgeist."
