One arm longer than the other, or one sleeve longer than the other??

Today was cold. I dug out my longsleeve shirt and got ready for work. It wasn't until I got to work that I remembered why I don't wear this shirt often.

The left sleeve is about 5" longer than the right sleeve.

I admit it. I shop at Reny's. Usually it isn't this obvious.

** No. I didn't wear my pajama pants to work. I took this picture when I got home.
