the advantage to the long shirt

I have discovered a new advantage to the trend being long shirts. I have heard several people say they like the new trend because it is better for the pregnant person. Being that I am not pregnant and don't plan on it for another few years, this is not an advantage to me. What have I determined to be so great about long shirts? If you forget to zip up your fly, no one knows!

Is this mannequin's fly down? Can't tell!
