Wouldn't it be: wearing a coat, over a sweatshirt, over a sweatshirt, over a shirt? In another picture, it looks as though the electric blue sweatshirt and the black one underneath both have zippers. Lots of layers. :) I layer like that too, as I'm always cold.
I like the picture of him in the blue dress shirt with tie a few posts above. Sharp!
Humankind. Be Both.
