I bought one of these military shirts this Summer and I'm still trying to figure out how to wear it. After I saw this gentleman at Pitti a few days ago I remembered I also had a photo of Robert R. wearing this same style.
After looking at the two images I now realize my shirt is too long. I need to shorten the length of my shirt to be in line with my wrist at the hip.
I think this is one of those truly versatile and inexpensive items that should be in everyones wardrobe.
