Season 1, Episode 3

For his daughter's birthday, Don puts together a playhouse in the backyard. Doing such strenuous work requires two things: a white tee and a shitload of beer. Besides his pre- and post-coitus gear, this is the most casual look we've ever seen from Don. Rocking the white tee and khakis channels his inner Stanley Kowalski, much to the delight of Betty and her friend.
