I bought a rather ridiculous amount of black socks and black t-shirts a few years ago, because I found a cheap range of each that seemed to be fairly good quality and fit well (I have small feet, the normal range of sizes in mens socks irritates me greatly). On the plus side, this reduces thinking in the morning, and means I have lots of them. On the down side, it means my laundry pile can take over entire rooms if I leave it until I'm nearly out of clean clothes. Which I tend to. :)
