I don't know either, but I like just the shirt thing better

sometimes he looks kind of cute with a jacket, but i also like him without it

I love him in Stamford he looks great with a blazer! And then he loses it when he gets back surprise surprise.

Either way he's Jim! *swoons*

he wears it both ways - he doesn't wear it in the office (cuz it's more relaxed) but wears it out of the office - traveling salesman, product recall, the job.
