It warranted such comments as "I don't want to offend you, but is that your ugly sweater?" and "I just LOVE your sweater!"
In the last case, the woman was serious and thought it was actually a cute sweater and I have serious questions about her fashion sense and also her sanity.
But the most fun time I wore my ugly sweater was when I wore it without pants.
Isn't that always the way it goes?
