I have worn stockings (panty hose) to work for so many years that I feel naked without them.  There are some of the "younger" women who have great tans who go without stockings during the warmer months, but, personally, I can't do it.  Even if I had a good tan on my legs (which I don't) I wouldn't feel comfortable without my stockings.  I even wear stocking-type knee-highs with pants.

Once I get  home though, the stockings are the first things to go.
