I have a shirt that is a regular button-up shirt… except it ALSO has buttons on the back! Kind of like this, except the buttons go up all the way up the shirt:

I wore it to work one day and a person in my office was so confused, they came up to me to ask how I had put on the shirt. It was extremely amusing.
