In episode 6 of season 4, Adaleen very shyly and modestly strips down into her full-length garments on her wedding night with JJ. You see her lay down on the bed, her bra is worn over the top — it just looks like long underwear. JJ also has his on, but they are under his plaid robe, which he begins to remove as the scene ends. Again, it just looks like long cotton winter underwear — not what mainstream LDS wear today, but very indicative of what would have been worn in the early 1900′s before modern comforts began playing a role in the design (which caused quite a rift in the older/younger generation at the time, as you might imagine).

And in episode 3 of season 4, Alby is dressing in a hotel room after a very fascinating discussion with Dale, that we will talk about in a future episode at some point. Alby puts on his garments there as “Roman” talks to him from the side of the room (ghost of Roman? Alby’s imagination/guilt complex? — powerful stuff!)
