Wearing mismatched pairs of shoes was the most common response to our Embarrassing Moments survey. There was also one woman who accidentally wore a mismatched pair of earrings -- a cute heart and a miniature set of handcuffs -- to an important meeting!
I was busy all day with meetings and projects and finally took a quick break with several co-workers. As we sat on benches outside of our office, one of our VPs gave me a funny look and said "Why are you wearing two different shoes?" I was horrified to see that not only were they different colors, but they were two entirely different styles.
