HOW TO GET PEGGY'S LOOK
Career-girl Peggy is the firm's first female copywriter since World War Two. Despite Joan's attempts to help her follow in her femme fatale footsteps, Peggy is more concerned with working hard and standing by her gender equality principles so her look is better suited to more conservative dressers and women who are larger on the bottom.
"Women looking to carry off a more toned down version of the Mad Men look will find Peggy a great inspiration," says Emma.
"Like her personality, her wardrobe is efficient, with a muted palette of wine tones, mustard, taupe and brown.
"Her skirts are longer and looser than Joan's and she doesn't like to draw as much attention to herself, opting instead of calf-length hems -- which is this season's skirt length and perfect for concealing fuller hips. Betty Jackson Black at Debenhams has plenty of pieces that hit the mark perfectly for this look."
Her key items are prim cashmere sweaters and cardigans teamed with pearls, and neck scarves are a must with tailored dress jackets and plaids or patterns on top to draw attention away from a larger bottom half.
Make-up should be fresh and flawless. A good tinted moisturiser and just a sweep of blusher is all that's needed to echo Peggy's youthful skin.
Hair is best swept into a high ponytail and tonged or left simple in a long bob.
