Track pants

Call them what you will, the pants that are circulating right now are just plain comfortable. With a fitted teeshirt, they are perfectly respectable for every moment you are not in the office.  Gap has some nice ones, and Uniqlo does too:

In fact, these drape pants have become so prominent, that I am starting to feel that more fitted pants look passé.  And they are SO comfortable.
