During February’s New York Fashion Week, designer Alejandra Alonso Rojas told WWD that she was switching things up and pivoting to release two cohesive collections a year in order to reflect her brand’s ongoing values of thoughtful craft and slow fashion. Fall 2025, a combination of her pre-season and mainline collections, was a direct result of that decision.

“It’s still growth [for the brand], but in an opposite way that helps save the planet, in a way,” Alonso Rojas said at the time, noting she had been researching more sustainable mill partners and fabrications had less environmental impact.

Now Alonso Rojas is set to reveal her follow-up spring 2026 collection on Wednesday — a sustainable collection in partnership with Amazon’s Climate Pledge.

During an exclusive interview with WWD, the Spanish designer explained it marks the next chapter in her brand’s evolution and upholds her commitment to sustainable, ethical fashion from beginning to end. Although the brand was built around long-lasting quality, responsibility, transparency and sustainable practices spanning from utilizing natural dyes and recycled fibers to working with small-scale factories, this milestone sees Alonso Rojas’ label transition fully to working exclusively with certified mills and sustainable fabrications. Furthermore, the brand has now joined the Amazon and Global Optimism Climate Pledge and is a member of the United Nations Fashion and Lifestyle Network.

“When I started the brand in 2017, I was a very different person and through the years, I’ve evolved into caring about what I’m putting in my stomach, what I’m putting into my skin,” Alonso Rojas said. 

“Instead of being disappointed by everything that’s happening on the planet, I thought I really needed to trust my intuition and listen to myself,” she said of questioning the impact she wants to make with her brand. “I’m not just making clothes for the sake of making clothes. I’ve always hated over producing. I always hate doing crazy sales. I hate the landfills. I’ve always really believed in a way more sustainable way of inheriting pieces and taking care of special pieces as treasures. I don’t feel they’re just for one season, but are pieces that you can always wear. I’m always focusing on a more timeless approach, rather than trend.”

Thinking about her sustainable lifestyle led to her doing a “huge detox” of her body spanning from looking into the labels of food to avoid chemicals and heavy metals and consciously eating meat that’s traceable to wearing sustainable makeup and skin care. This also naturally led to thinking more deeply about the clothes she puts on her body, and that she designs for the global woman.

“When hard times come around, you can either be scared or continue with your doing. I feel like it was an inflection moment for me where I knew that we had spoken about [sustainable practices], and internally, we knew we were doing a lot of that, but it’s something that we hadn’t made a statement about. I thought it was really important that if we were gonna commit to it, we had to do it fully,” she said. 

During the initial stage of designing her spring 2026 collection, Alonso Rojas told her team, “We’re moving into a full sustainable model, where every fabric is going to be sustainable and every mill that we’re working with has to be certified.”

Although it was a big pivot moment, it came naturally. Alonso Rojas is now working with six certified mills that share her commitment to human dignity and leadership in environmental and social responsibility, craftsmanship and sustainability. These mills include Kaneyo and Hasegawa in Japan, Jean Bracq in France, Soktas in Turkey and Gruppocinque and Be.Mi.Va in Italy.

“Yes, there’s some partners that we have not been able to continue partnering with — not because of the mills’ practices, but it was more because the qualities of the fabrics they were making were not fully sustainable. Every person I’ve always worked with, I believe they had good practices as in human rights for their workers. But I feel some mills are going to take longer, and right now I’m only going to partner with those mills that have the certifications,” she explained, noting that she is continuing to work with her original certified leather mill and is having ongoing conversations with the handful of mills she stopped working with. “We’re just putting them on hold until we know they really have their sustainability practices up and running.”

Each of Alonso Rojas’ garments is produced in limited runs or cut-to-order to minimize excess inventory and focus on quality and attention to detail. In addition, the brand has partnered with New York-based nonprofit Fabscrap to responsibly dispose of unusable fabric scraps and source post-consumer textiles for future projects; is investing in upcycled and experimental design with archived collection’s textiles, and will be releasing limited capsule collections of leather accessories and handbags crafted from leather remnants, dead-stock trims and atelier offcuts. Furthermore, she will continue offering clients the ability to give their own Alejandra Alonso Rojas worn garments a new life with the option to re-dye or have their items embroidered.

Additionally, more than 95 percent of the brand’s production takes place in New York, which minimizes its carbon footprint, and a majority of its workforce is women, both in the U.S. and abroad, and in support of local economies. Woven and cut-to-order styles are produced in Manhattan’s Garment District and hand-knit and crochet styles by women artisans are made in Brooklyn while the other 5 percent include luxe cashmere machine knits in Italy and Camariñas lace crafted by female artisans in Galica, Spain.

Alonso Rojas explained these changes speak to the three important pillars of her pivot: transparency, responsibility and enduring quality.

Regarding transparency and messaging to consumers, starting with spring 2026 each garment will feature a QR code that customers can scan to see its fabrication, origin, manufacturing details, sustainable certifications and details about the artisans that crafted the piece.

Her garments are now crafted exclusively in certified fabrications including FSC Certified viscose and triacetate; closed-loop and FSC certified Naia acetate; GOTS, Okeo-Tex 100 and regenerative farming cotton; European flax linen; GRS, GOTS, FSC, Okeo-Tex 100 lace, and recycled and GRS-certified polyester. Furthermore, she explained that her bestselling hand-draped, bias slipdresses “will not change” aesthetically, but will be crafted in sustainable GOTS or Okeo-Tex silk in the future. 

“While we go into a fully circular model, which is what we want to move into with the next generation traceability practices, I felt like the QR code was a really good start,” she said.

When it comes to working with her current retail partners, Alonso Rojas said she wants to work with buyers to divide her two main seasons into drops. She also hopes the brand’s pivot will be a “differentiation point” to enter new retailers and wholesalers with sustainability departments.

Outside of her upcoming intricate, special pieces for spring, Alonso Rojas said she projects prices will remain in line with her current luxury range of separates from $925 to $1,795; dresses from $1,195 to $1,995; tailoring from $1,295 to $2,395; evening gowns from $2,395 to $3,495; hand-worked gowns around $5,000, and artisanal hand-crochet pieces between $1,695 and $1,895.

“I really want to dedicate the time to develop two very special collections that can be shipped throughout the different months. I believe in a more circular model, so maybe some pieces are to be kept and buyers can keep reordering them if they’re performing,” she explained, noting she’s been working to elevate each collection with more specialty styles alongside brand classics.

“I want to present designer fashion, true creativity and craftsmanship into this collection and moving forward. I feel like people sometimes think that sustainable things have to be more simple or casual, but I want to present it in a very different way, where it’s very elevated,” she said, pointing out sketches of new voluminous gowns and corsetry looks, prints designed in collaboration with French artist and Alonso Rojas’ friend Philippine de Richemont, and custom sustainable lace and embroidery swatches for spring 2026.

“The beauty of it is the brand is not really changing but amplifying the sustainability aspect. You can get a fully sustainable gown and know where it’s coming from, that it will be good on your skin and is good for the environment. Again, it’s a piece that doesn’t have to end up in a landfill the next month, although most of the fabrications we’re working with, if not all of them, are actually biodegradable,” she said.
