And now I know why they are called slips. Many moons ago while walking down 23rd Street, off Lex, I felt something tugging at my knees. To my horror I saw that my slip had...slipped, and was at my ankles. Clearly the elastic had snapped, allowing the offending undergarment to slither down. So I just stepped out of it and kept walking.
As you can see above, that is my slip on the floor of my office. WTF?
Is this common?
