The great pleasure of this season's fashion has been found in watching Megan dress perfectly for every occasion. Whether she's pitching ideas to Don in a collegiate navy turtleneck and striped skirt or saving an account at dinner in a sparkly mini, she always strikes the right balance between business and bombshell. In last night's episode, Megan uses her style know-how to give Sally a mod make over, putting her in a silver and gold go-go outfit, complete with white leather boots and a high ponytail. Sadly, Don immediately tells Sally to loose the boots and makeup. Meanwhile, Peggy takes Joan's advice to buy something special in anticipation of Abe's "proposal," and she purchases a hot-pink dress (instead of her usual plaid pinafores). Roger's ex-wife, Mona, makes a brief but welcome comeback in a sequined shift, but Roger is taken with Megan's gorgeous French–speaking mother, who seduces him in her black gown with rhinestone neckline. See all of the episode's best looks in our fashion recap.
Mona's sparkly dress
Foxy and free in a sequined shift, Mona listens as Roger tells her about his acid "trip." Then she sideswipes him by declaring, "I thought you had married Jane because I had gotten old. And then I realized, it was because you had."
Don's striped P.J.s
Perfect for reading James Bond in bed.
Megan's navy turtleneck and striped wool skirt
Megan knows how to keep things office-appropriate and on-topic. But after she gives Don the idea for Heinz, he still wants to make out with her.
Peggy's plaid dress over a collared shirt
Looking very "Catholic schoolgirl," Peggy barges into Joan's office once again seeking advice, sartorial and otherwise.
Joan's purple dress with scalloped collar
She might be moving on with her life, but her wardrobe is stuck in the earlier part of the decade.
Peggy's proposal dress
For the big occasion, Peggy chose the most Joan–like dress she could — solid pink, empire waist, round neckline — but it didn't quite get the results she had hoped for.
Peggy's plaid coat and unflattering hat
After the anticlimactic dinner, Peggy returns to reality with her de rigueur plaid and an unfortunate choice of headgear.
Megan's dazzler at dinner
In a silver-and-gold mini, she literally proves her worth (like Don's ideal Bond Girl) by saving the Heinz account.
Sally's go-go outfit
It takes a cool, young stepmom to know just what Sally would want to wear to her dad's big awards ceremony. And it takes a stern father to ruin it by demanding she take off the boots and makeup.
Megan's chic parents
In a stunning trompe l'oeil gown and slightly disheveled tux, this May-December pair gives us a glimpse into Megan's psyche and her inherited sense of grace.
Peggy's "housewife" dress
Wearing oven mitts and an apron, this is the most domestic we've ever seen Peggy. She fools no one, least of all her mother, who warns her Abe will use her as "practice" until he decides to get married.
A retreat to children's sleepwear, after a harrowing night on the town.
