In the cavernous Brooklyn warehouse where “The Marvelous Mrs. Maisel” was filmed there are towers of pillbox hats, double-stacked racks of dresses and coats in rainbow order, and vision boards teeming with fabric swatches. At an October set visit during the shooting of the comedy’s latest season, Emmy-winning costume designer Donna Zakowska gave marching orders to her team in order to translate the characters’ emotions and aesthetic tone of each scene. Over five seasons, Zakowska says she’s dressed nearly 50,000 principal actors and extras for Amazon Prime Video’s hit show, which launches its final season Friday. “Maisel” follows a New York City housewife who makes an unlikely turn to standup comedy in a journey of self-discovery after her husband’s infidelity blows up their conventional life. Before filming, Zakowska gave each player a once-over to ensure every shoe, brooch and belt looked right. When seeking inspiration, Zakowska often referred to what she called the “Maisel map” – images of star Rachel Brosnahan’ s signature looks and color palettes from previous seasons – across from a wall of her latest sketches.
