Sézane Became a French-Girl Fashion Phenomenon. Now Its Founder Is Editing the Formula

Morgane Sézalory built Sézane at such a relentless pace that, for years, the founder had little time to step back and take stock of what it had become. Twenty years ago, the self-taught entrepreneur set off a fast-moving chain of events when she began selling vintage finds online. After developing a following, Sézalory launched the Paris-based brand, with clothing inspired by her favorite pre-loved pieces, in 2013. Over the last decade, she has grown the name from one of France’s earliest digitally native fashion brands into a global business known for romantic blouses, covetable knitwear, and a "je ne sais quoi" version of Parisian style that women worldwide wanted to buy into.

None of it, according to Sézalory, happened as part of some grand master plan. “When I started, I didn't know I would one day run a company like Sézane…I never dreamed about creating a brand which would be international,” she tells Marie Claire. “I put so much energy and heart and passion [into it] without any strategic plan. So everything happened very spontaneously.”

Now, Sézalory is ready to be more intentional about turning that lightning-in-a-bottle success into a “forever brand.” The result arrives this fall as a “new chapter” for Sézane: refreshed visuals including a new logo, a redesigned digital experience, new store concepts, more assertive ready-to-wear, a greater emphasis on handbags, and a vintage project that will take Sézalory back to where she started.

While an overhaul might sound counterintuitive, given the success of the brand that has since opened 20-plus storefronts in Europe and the U.S, Sézalory is clear that this is not a complete 180. “The idea is not to change everything,” she says. “I wanted to edit what Sézane was.” The question for her became: “What do we want to keep? What do we want to let go? And what do we want to add?”

That process kicked off two years ago, when Sézalory took a step back from the company. While looking after a sick family member, she had space to see Sézane differently for the first time. “I realized that now I was able to create the brand of my dream,” she says. “It’s not that I didn’t do what I wanted before. It is just that maybe I never had time, or I never had the same resources that I have today.”

What followed was an inventory check. Sézalory approached the brand with the curatorial eye that marked the beginning of her career, deciding what deserved to be there after more than a decade of new collections, bestsellers, brand collaborations, and category expansions. “As a brand, when the years pass, sometimes you keep too many layers,” she says. “You don’t take enough time, or you don’t have the courage to edit and make it more lean.”

For Sézalory, that accumulation had started to feel less like growth and more like a constraint. “A lot of the pieces we are not keeping are pieces from 10 years ago or eight years ago,” she says. “Year after year, sometimes you don’t question why you keep them. And the fact that you keep them doesn’t leave room for the new ones that you would love more.”

That doesn’t mean Sézane is abandoning the signature aesthetic that first set it apart and put it on the map. The white shirts, cashmere sweaters, and trench coats remain. “Some of them, we kept them as they were because they are perfect already,” Sézalory says. “And some of them we realized we want to make a new version which looks more like us today.” The shift is most apparent in the materials, proportions, and silhouettes: fabrics are weightier, with higher-end wool and leather; volumes are more pronounced, from balloon sleeves to exaggerated shoulders and billowing capes; and shapes feel sharper and more architectural. “It is still Sézane,” she says, “but it’s Sézane with more maturity, more confidence.”

The distinction matters to Sézalory because, in many ways, the brand’s evolution mirrors her own—she always considered herself as much a Sézane customer as its founder. She was in her early twenties when she started selling vintage; now in her early forties with three daughters, she describes the last two decades as an “education” during which she “was still building foundations” of the business. Now the groundwork is laid, she's ready to focus on the interior. “It was like, school was over for me. I had learned about everything, and I was ready to become a professional and a more mature version of myself and of the brand.”

That maturity is most evident in the restraint of the Fall 2026 collection, whose first drop arrived on August 23. For it, the clothes trade some of the boho romance associated with Sézane for dramatically high collars, sculptural shoulders, oversized outerwear and knits, and rich textures. The palette is pared-back too, revolving around chocolate brown, olive, taupe, navy, ecru, and rust rather than the florals and brighter prints longtime customers might expect.

Recalibrating a brand with exceptionally loyal customers—who have spent years developing their own ideas about what makes something distinctly Sézane—carries an obvious risk. In the days leading up to the launch, some of its fans were already voicing their unease online. On Reddit, shoppers lamented the lack of prints and color. Meanwhile, others worried that the oversized, heavier use of leather, and higher-priced accessories signaled that Sézane was moving away from the femininity and accessibility that attracted them in the first place. On the other end, fans welcomed the prospect of smaller, more refined collections, higher-quality materials, and a “shop less but better” approach to newness.

When I spoke to Sézalory in July, she seemed prepared for the possibility that not everyone would immediately be on board. “I’m not afraid of losing the Sézane customer,” she said, adding that she believes the new direction will ultimately amount to “a better version of Sézane” that its shoppers will come to embrace.

More personally, later this year, this new era marks a return to her first “love”: vintage. Sézalory credits years of curating secondhand clothes with providing her an education in design before she had any formal training: “[It] taught me everything about the history of fashion, but also fabrics, shapes, and style.” This fall, she’ll reunite with that passion through one-of-a-kind vintage fashion, accessories, and objects edits, assembled by Sézalory and members of the brand’s creative circle. The drops will align with Sézane’s Call of the 21st initiative when, on the 21st of every month, 100 percent of net sales from one "solidarity" product and 10 percent of the day’s revenue are donated to its social impact fund DEMAIN.

More than nostalgia, the project reflects the larger philosophy behind Sézalory’s reset. “I wanted to bring back this idea that the way we make Sézane is to create pieces which will last…be there in 25 years or 50 years,” she says. “I love long-lasting choices and not choices that we won't like just two seasons after [they launch].”

For Sézalory, longevity also depends on preserving the position Sézane has long occupied between mass-market fashion and luxury. The company is investing in higher-quality materials and moving slightly upmarket on some pieces, but she is adamant that it's not abandoning the accessibility that helped build the brand in the first place. “It doesn’t have to be unaffordable to be desirable,” she says. “I think it’s very important for me to keep being this brand.”

After two decades of building Sézane by adding to it, Sézalory is betting that making it last will require knowing what to leave out.
