Arielle Cooper-Lethem is the costume designer for Lena Dunham’s hit new show, Too Much. The hilarious and heartfelt rom-com, led by Hacks star Megan Stalter as Jess and The White Lotus star Will Sharpe as Felix, debuted on Netflix in July. This week, Cooper-Lethem joins Who What Wear Editorial Director Lauren Eggertsen to tell us what it was like curating Jess’s maximalist wardrobe of vintage nightgowns and lacy bloomers, as well as how Kurt Cobain inspired Felix’s grungy, androgynous Londoner style. Plus, Arielle tells us about If Only If, the independent British brand behind Jess’s iconic red, frilled nightie that fans bought en masse.
