Leigh Ann Cobb and Hannah Yesmunt will be the first to tell you they know nothing about the swimwear industry.
That makes their mission to disrupt it all the more fascinating.
Cobb and Yesmunt are the co-creators of Saint Andro, a Grand Rapids-based fashion startup pushing the boundaries of what swimwear can look and feel like and who it’s for. For the past year-and-a-half, the pair have been exploring, researching, prototyping—and, as of this month, launching—a collection of androgynous swimwear that emphasizes practicality over chic, ethics over profit and personalization over fast fashion trends.
Both are coming to the industry as outsiders. Yesmunt holds a degree in French language from Grand Valley State University and works as a logistics specialist for Wolverine Worldwide. Cobb is a commercial photographer who graduated from Kendall College of Art and Design of Ferris State University with a Bachelor of Fine Arts in Drawing with a Printmaking emphasis.
What’s more, they’re launching a fashion line from the heart of the Midwest.
“Swimwear brands are usually coastal or tropical; you don’t see a lot of visuals that are Michigan,” said Cobb. “We are leaning fully into the practicality and functionality of our Midwest roots to make suits that do so much more for the wearer than help them look good at a resort.”
Like the brand, Saint Andro’s origin story reflects a shifting world. Early in the COVID-19 pandemic, a restless Yesmunt decided to do something about her lingering dissatisfaction with contemporary swimwear. She taught herself to sew and set about creating the swimsuit she wanted to see: one that was comfortable, functional, durable and most importantly - tailored to both her body and her queer identity.
When Yesmunt shared the results on Tik-Tok, she found she was far from alone. The video drew thousands of likes and comments from people all over the world who shared her frustration and applauded her vision.
One of those people was Los Angeles-based pattern maker Shilo Byrd, who expressed interest in turning the one-off design into a producible garment. Byrd and Yesmunt began working on a prototype, and Yesmunt soon realized that she wasn’t only making a swimsuit anymore—she was building a brand.
Enter Cobb, who specializes in helping companies develop a visual language around their brand. When Yesmunt contacted her about shooting promotional photography, Cobb said she immediately felt drawn to the project.
“I grew up on a lake, and every swimsuit I’ve ever had has been flimsy, cheap, and uncomfortable. When I saw what Hannah designed had so much more practicality and attention to quality, I immediately wanted to purchase it,” she recalled.
More than just the product, the larger mission behind it sparked Cobb’s interest. Using the creative problem-solving and critical thinking skills she cultivated at KCAD, she’d already started a successful freelance business and learned firsthand what it takes to sustain it. With Saint Andro, she saw an even deeper opportunity to translate her creativity into entrepreneurship.
“My KCAD professors were great at showing me what’s possible when you develop the skills and perspective not just to create but to create in a way that connects meaningfully to the world around you,” Cobb said. “When Hannah and I first talked, I was at a point in my career where I was looking to be a part of building something bigger than my own brand, something that had a positive impact and would feel good at the end of every day.”
What started as an initial discussion quickly blossomed into a fully-fledged business partnership, with Yesmunt leading design and production and Cobb as creative director. The idea of who Saint Andro could serve also started expanding.
“Beyond addressing the lack of swimwear options in the queer community, we started thinking about older women who might feel very seen and comfortable in what we were making. We thought about the compressive nature of swimwear and how that could also benefit neurodivergent individuals with sensory issues,” said Cobb. “There were so many ways we could celebrate humanness with Saint Andro that we just weren’t seeing from other brands out there.”
Saint Andro’s recently released first collection is a mix-and-match lineup, including a sleeveless two-way compression top, a zipped cropped top, a lined ripstop short, a reversible biker short, and separate sleeves that can be worn with both tops. All the pieces are made of double-knit fabric that stretches easily, resists wear and tear, blocks UV rays, and insulates. They’re designed to conform comfortably and provide support to the wearer’s body, last a long time, and be functional in both warm and cold seasons for activities like hiking, biking, and running in addition to swimming.
When it comes to fit, the garments are offered in a size range of XS to 5X. Not only is that level of inclusivity rare in the world of swimwear, Yesmunt and Cobb also worked with Byrd to bring a heightened intentionality to the process of making a production pattern for each size.
“We learned that garment prototypes are usually created in a size small. Once the small pattern is finalized, the pattern maker simply scales it up into the other sizes and calls it good,” Cobb explained. “We knew that we needed to do better.”
Prototyping garments, especially using these kinds of specialized fabrics, isn’t cheap. To minimize costs and material use, Saint Andro employed an innovative digital modeling software called CLO, which allowed them to create virtual patterns and test them on virtual bodies with unlimited control over all parameters.
“We were able to do extensive testing and learning before we even touched a scrap of physical material,” Cobb said. “It saved us so much time, energy and resources, but more than that, it helped us ensure that we had created the most inclusive designs possible before moving forward.”
Once they had initial physical prototypes of each size, Yesmunt and Cobb traveled to Los Angeles, where they held multiple rounds of test fit sessions on real people, making observations and soliciting feedback to refine the designs further. What they learned helped inform the final patterns for the diverse size range in their first collection and the extensive fit guide available on their online store.
“We want people who buy our swimwear to put it on and have this immediate sense of ‘wow, I feel good in this,’” said Cobb. “They shouldn’t have to think about returning it even for a second.”
Sustainability and ethical production are also at the core of Saint Andro. Each garment in the first collection blends recycled polyester and spandex. Yesmunt and Cobb have goals to explore the use of biodegradable materials and a customer take-back program down the road to reduce the brand’s environmental impact further.
Everything is manufactured in Los Angeles at a women-owned production facility emphasizing ethical wages and construction methods that minimize material waste, with material scraps from tops and bottoms used to create the add-on sleeves.
“We’re learning what the industry standard is for sustainable and ethical practice in fashion and looking for opportunities to go further,” Cobb said. “We’re always going to be learning and growing along the way, and that goes for every facet of Saint Andro.”
“Authenticity” has long been a branding buzzword. But much of what makes Saint Andro’s claim to it ring truer than most comes from the transparent way they’ve evolved their ideas. Yesmunt and Cobb have publicly documented nearly every stage of their journey, from posting customer research and prototype experiments to social media to being open and honest about the challenges of entrepren
