in (one's) stocking(ed) feet
Wearing only one's socks or stockings, but not one's shoes. I had just run out to grab the newspaper, but the door locked behind me. Now I'm stuck outside in my stockinged feet!

Wearing socks or stockings, but not shoes, as in I got locked out of the house in my stocking feet. [First half of 1800s]
