I don't like laziness which is exactly what it is. They used the white long sleeve from his formal wear and then used a painted on vest. He's probably still wearing the same black pants from the formal wear as well. It's disappointing.
They're actually pretty different shirts, Gregg. Look at them closely. The formal wear shirt is nicely ironed while this shirt is all puffy. Now look at the wrists, they're different as well. Along with this shirt having no collar, no buttons, and goes down to his chest.
