dudes use to wear 1/2 shirts too and it was cool , not sure anyone will remember that though
1. It was NEVER cool. It may have been socially acceptable fashion, but NOT cool.
2. If I saw it, I blocked it out. Last thing I need to see is some dude's tummy.
Now, to fix the mental image you have forced upon us all, allow me a moment's diversion:
Much better.
