I'm growing old, and I have not mastered the art of putting undershirts correctly on. Almost always, I make sure to turn them right side out. Then there is the issue of distinguishing between front and back. The collar at the back is usually higher and thicker. Why? If I put the shirt on backwards, I have to take it off and try again. Why can't the front and the back be the same? In fact, why can't the inside and the outside be the same? We're talking about a garment that is normally invisible.
My occasional ineptness isn't the only reason that undershirts bother me. I'll tell you about the traumatic side tomorrow.
