Fat Betty makes only one brief (but highly satisfying) appearance on last night’s Mad Men, when she discovers her mother-in-law Pauline passed out in a Seconal–induced stupor next to a half-eaten box of crackers on the living room sofa. (What goes around comes around, Pauline!) Rest assured, Betty shows no signs of slimming down and wears an impressive napkin of a dress with pearls and white gloves. Meanwhile, Joan’s husband, Greg, returns home from Vietnam, giving Joan a great excuse to parade around in bosomy dresses and Joan’s mom an occasion to bust out her pink, lacy fascinator. Meanwhile, new hire Ginsberg experiments with seersucker, Peggy gets drunk while wearing a beige tie, and Sally looks adorable as usual. See all the episode’s best looks in our fashion recap.
