I am obsessed with layering. This is partly out of necessity, because I have a 9 to 5 job in a very conservative corporate environment, in addition to my 5 to 9 job in media. This means I am likely running to cover an event right after work, and I need to be able to go from conservative Jessica to Not Carrie Bradshaw Jessica quickly (although the two are not vastly different). Adding or taking away a layer helps me to avoid carrying a large suitcase around the crowded streets of New York to do a Diana Ross level wardrobe change.
