For me, t-shirts are every three days. Underwear and socks are daily. As for your comment, I responded the same way as you, initially. Someone challenged me on my thinking, though, and I've come to the conclusion that they were right. First off, how often do you have a leather jacket cleaned? Right. It just doesn't warrant this, given the nature of the material and the use. Socks and underwear smell by the end of the day. Try wearing a pair of jeans for a few weeks and see what they smell like. You might be surprised that they're generally fine (barring any spills, etc.) Raw denim manufacturers often suggest a 6 month wash schedule, as it helps the denim wear in naturally. Meanwhile, research states that there aren't any health risks for doing so: http://news.nationalpost.com/2011/01/19/not-washing-jeans-for-15-months-ok-healthwise-at-least-study/ http://news.nationalpost.com/2011/01/19/not-washing-jeans-fo...
