When Lily Collins’ character Emily steps onto the screen in a vivid red blazer, viewers notice more than just a fashion choice—they see a backstage revolution. The garment, designed by Emmy‑nominated costume creator Marylin Fitoussi, marks the culmination of a season where a classic bob haircut sparked a cascade of bold colors, Italian‑inspired silhouettes, and a workflow that leaned heavily on automation and digital prototyping.
Fitoussi, who has shaped Emily’s wardrobe since the series debuted, explains that the bob was a narrative device: a fresh haircut signaled a new chapter for the Parisian protagonist. "The haircut let us push the fashion further, bolder," she told Variety. Yet the visual leap was not achieved with sketchbooks alone. Over the past year, Netflix’s production teams have integrated cloud‑based design platforms, AI‑assisted color forecasting, and virtual fitting rooms to accelerate costume development. The result? A three‑week sprint that delivered a full‑season collection, including the standout red blazer by Barbara Bui, without compromising creative intent.
The technology adoption is evident in three key stages. First, designers upload mood boards to a shared digital asset library, where machine‑learning algorithms suggest complementary palettes based on historical data from runway shows and streaming trends. Second, 3‑D garment simulation tools allow Fitoussi to visualize how fabrics drape on a virtual model of Collins, reducing the need for multiple physical prototypes. Finally, an automated approval workflow routes designs to the series’ creator Darren Star and the production designer in minutes, rather than days, ensuring rapid alignment on narrative symbolism.
Beyond speed, these tools reshape the creator economy. By freeing designers from repetitive tasks, they can focus on narrative‑driven decisions—like assigning the red blazer as a "manifesto" of confidence. The blazer’s backstory, tied to Emily’s evolving relationship with mentor Sylvie Grateau, becomes a layered storytelling device that resonates with audiences while showcasing how digital pipelines can preserve artistic nuance.
Industry observers note that this blend of fashion and tech mirrors a broader shift in media production. Automation‑driven media infrastructure is enabling streaming giants like Netflix to scale high‑quality visual storytelling while managing tighter budgets. Costumes that once required weeks of physical sourcing now benefit from virtual sourcing, reducing waste and carbon footprint—an outcome that aligns with sustainability goals across Hollywood.
Fitoussi’s Emmy nomination for Episode 10, which features a Venice Fashion Week homage, underscores the credibility of this hybrid approach. The episode’s aesthetic draws from the Palio di Siena, a horse race famed for its vibrant city‑ward colors, and was reinterpreted through a digital collage of pastel and bold hues. "I’m a patchwork lover," Fitoussi recalled, noting how digital tools helped her blend French, American, and Italian influences into a cohesive visual language.
The implications extend to fashion brands watching the series. The red blazer sparked a surge in online searches for Barbara Bui, prompting retailers to explore AI‑guided inventory planning to meet sudden demand spikes. In turn, the fashion industry gains a testbed for rapid trend validation, a practice that could become standard as streaming content continues to dictate consumer style.
While the technology stack behind Emily’s wardrobe is sophisticated, the core narrative remains human: a character shedding inhibition, a designer translating confidence into cloth, and a platform that now has the tools to deliver that vision faster and greener. As streaming services double down on immersive storytelling, the marriage of costume design and automation may become a template for future productions.
