Last night’s Mad Men finale was a poetic conclusion to an explosive season, and the outfits were a nice mix of new (Peggy) and old (Joan). Marie made a good showing in her trim monochromatic dresses and skirt-suits during her visit for “Easter ” (actually, Roger Sterling), while Megan hit a new low by staggering around drunkenly in lacy floral pajamas.
