Sylvie (Philippine Leroy-Beaulieu) and Madeline (Kate Walsh) have a power clash this season, which culminates at Pierre Cadault's retrospective, where they both show up in the same dress, albeit accessorised differently. The look comes courtesy of designer Stéphane Rolland, who makes a cameo in the episode.
"I chose [the dress] because there is a very devilish side to Sylvie at the time," Fitoussi explained to Netflix. "I wanted it very minimalist; a black dress with an arch that was completely innovative in its construction. We had to make a double of this dress for Kate Walsh, who arrived a few days before the shoot, so we all crossed our fingers that it would be as beautiful on her body as it was on Philippine's physique, and it was." Walsh's look is further exaggerated with an Elsa Peretti snake necklace meant to feel a little tacky and poke fun at her American sense of style.
