The Swimsuit Shortcut: 5 Lessons Sustainable Swimwear Taught Me About Niche Marketing
I found myself in a digital rabbit hole a few nights ago. I was trying to buy swim trunks—not exactly a high-stakes, Series A-level decision. But as a founder, you start to see patterns. And what I saw wasn't just a bunch of recycled polyester; it was a full-on masterclass in modern business strategy.
We're all fighting for attention, right? We're all trying to lower our CAC, increase our LTV, and build something that isn't just a leaky bucket. We read the same HBR articles, listen to the same podcasts. But the sustainable swimwear market? It's like a hyper-speed case study of every single one of those lessons, playing out in real-time.
The topic of "Sustainable Swimwear for All Body Types" probably sounds like a B2C lifestyle piece. But I'm telling you, as one operator to another, the principles that are causing brands in this space to either explode or implode are the exact principles we need to be applying to our SaaS products, our agencies, and our e-com stores.
Why? Because this niche perfectly combines two of the most powerful, and most misunderstood, forces in business today: Sustainability (a long-term business model, not just a fabric) and Inclusivity (a market expansion strategy, not just a moral high-five).
So grab your coffee. Let's ignore the beach for a second and focus on the business. This is what the swimwear world can teach us about building a brand that actually lasts.
Why Are We Talking About Swimwear? The Business Case
Let’s get this out of the way. The global sustainable swimwear market was valued at around $8.7 Billion in 2024 and is projected to climb. This isn't a tiny, feel-good niche. It's a shark tank.
But the real story is why it's growing. It's not just "green" consumers. It's a perfect storm of market forces that apply to every single business, including yours.
The Old Model: "One Size Fits None"
For decades, the swimwear industry (like many industries) operated on a simple, flawed model: define a single, narrow "ideal" customer and market exclusively to them. For swimwear, this meant supermodels on a beach. For B2B SaaS, it might mean the "Fortune 500 CIO."
The result? A massive, underserved, and frankly, resentful market. You had millions of people with money to spend who were actively ignored or, worse, made to feel like they didn't belong. This is the business equivalent of leaving 80% of your Total Addressable Market (TAM) on the table because it's "not your core demo."
The New Wave: The Trillion-Dollar Opportunity in Niche
Enter the disruptors. Brands like SKIMS, Good American, and countless smaller DTC brands didn't just decide to be "nice." They spotted a colossal market failure.
They understood a few key things:
- Pain Points are Profit: SKIMS's founder, Emma Grede, talks about how they built the brand by first listening to customer feedback and solving actual pain points. They didn't invent a problem; they solved a real, pre-existing one.
- Authenticity is the New Currency: A 2024 Kantar study found that 75% of consumers say a brand's diversity and inclusion reputation influences their purchase decisions. Consumers have finely-tuned "authenticity detectors" and can spot "purpose-washing" (like greenwashing or rainbow-washing) from a mile away.
- Inclusivity Drives Action:** It's not just a feeling. A "Think with Google" report found that 64% of consumers took some sort of action (like visiting a site or making a purchase) after seeing an ad they considered to be diverse or inclusive. That number jumps to over 80% for groups like Latinx+ and LGBTQ+ consumers.
The lesson? "Sustainable Swimwear for All Body Types" isn't a product description. It's a go-to-market strategy. "Sustainable" is the promise of authenticity and long-term values. "All Body Types" is the market-expansion strategy of radical inclusivity.
Lesson 1: "Sustainable" Isn't Fabric, It's a Business Model
When most founders hear "sustainability," they think of supply chains, recycled materials (like ECONYL® regenerated nylon, which is common in this space), and carbon offsets. That's all part of it, but it's a surface-level reading.
True sustainability is about the Triple Bottom Line (TBL), a concept from Harvard Business School that's more relevant than ever: People, Planet, and Profit.
In the old model, you'd sacrifice the first two for the third. The sustainable model argues that Profit is the result of caring for People and the Planet.
As an operator, here's how to translate this:
- Planet = Supply Chain Efficiency & Risk Reduction. Using recycled materials isn't just good PR; it's a hedge against volatile raw material prices. Building a transparent supply chain prevents the kind of brand-destroying scandals that... well, destroy brands.
- People = Talent Acquisition & Customer Loyalty. This is about your internal and external community. Brands that treat their employees well (People) attract better talent. Brands that treat their customers with respect (also People) build a community, not just a customer list. This is your moat.
- Profit = The Long-Term Win. This model focuses on Long-Term Value (LTV) over short-term conversion. A customer who buys from you because they share your values is stickier, less price-sensitive, and a more powerful evangelist than one who just clicked a 20% off coupon.
The sustainable swimwear brands that win aren't just selling a "green" product. They're selling transparency. They're proving that their values are woven into their operations, not just stitched onto a tag. This is the antidote to "purpose-washing," and consumers are willing to pay a premium for it.
Lesson 2: "All Body Types" is How You Redefine Your TAM
This is my favorite part. As founders, we're obsessed with our Total Addressable Market. We put it in our pitch decks, we argue about it in board meetings. But most of us define our TAM by looking at the existing market.
The inclusive swimwear market proves that the biggest opportunities lie in the Unaddressed Market.
Brands like SKIMS didn't just take a slice of the existing shapewear/swimwear pie. They baked a new, bigger pie. They did this by focusing on two things:
- Solving Unspoken Pain Points: The legacy brands' message was, "Change your body to fit our clothes." The new brands' message is, "We made these clothes to fit your body." This is a profound shift from aspirational marketing to empathetic marketing. They solved problems of fit, comfort, and confidence that incumbents had ignored for decades.
- Marketing as an Invitation: By showing a true diversity of body types, ages, and ethnicities in their campaigns, they sent a simple, powerful message: "You are welcome here." For millions of consumers who had never seen themselves reflected in marketing, this wasn't just a product; it was a visible sign of belonging.
This isn't a "woke" strategy; it's a brilliant land-and-expand strategy. By catering to the underserved edges, they created a gravitational pull that pulled in the "core" market as well. Everyone wants to be part of a brand that feels real, authentic, and confident.
The lesson for your startup? Stop fighting over the 10% of the market everyone else is targeting. Find the 90% everyone is ignoring. What are their "misfit" pain points? What simple change in your product, marketing, or onboarding would make them feel seen? Solve that, and you don't just win a customer; you build an army of evangelists.
The Operator's Playbook: 5 Ways to "Fit" This Strategy to Your Startup
Okay, theory is great. But how do we apply this to our non-swimwear-based businesses? Here is the practical, five-step playbook.
1. Conduct a "Fit" Audit (Before You Do Anything)
Just as a swimwear brand needs to understand different body types, you need to understand your unaddressed market. Go beyond your current customer personas. Who is not buying from you, and why?
- Action: Run a "pain point" survey, but send it to people outside your core demo.
- Action: Read your 1-star reviews. They are a goldmine of "misfit" problems.
- Action: Look at your website analytics. Where do people drop off? That's a point of friction—a "bad fit."
2. Weave Your Values into Your "Supply Chain"
Your "supply chain" might not be fabric mills, but you have one. It's your tech stack, your hiring process, your content pipeline, your customer service SOPs.
- SaaS: Is your code accessible to people with disabilities? (Planet/People)
- Agency: Do you have transparent pricing, or do you hide it? (Authenticity)
- All: Do your job postings use inclusive language to attract diverse candidates? (People)
Pick one thing that aligns with your brand's core values and make it non-negotiable. That's the start of your authentic sustainable model.
3. Stop "Purpose-Washing" and Start Doing
Consumers (and B2B buyers) are tired of the "In these uncertain times..." emails. Don't just post a black square or a green logo. Authenticity is action.
- Instead of: A vague blog post about "Our Commitment to X."
- Try: "This year, we're changing our packaging to reduce waste by 30%. Here's the plan, the cost, and why we're doing it. We'll post an update in Q3."
Be specific. Be transparent. And most importantly, report on your progress—even if you fail. Failure is more authentic than a slick, empty promise.
4. Market to the Niche, Sell to the Masses
This is the secret of inclusive marketing. When you create a solution for a specific, underserved niche (e.g., a SaaS tool for non-profit grant writers), you solve their problem so perfectly that they become your biggest fans.
But a funny thing happens: the "core" market (e.g., all grant writers) sees the precision, quality, and empathy you put into that niche solution and realizes it's a better product for everyone. The U.S. Small Business Administration (SBA) has guides on this, noting that defining your target market in detail is the key to a competitive advantage.
5. Create a Relentless Feedback Loop
The most successful inclusive brands, like SKIMS, are built on a foundation of customer feedback. They don't guess what people want; they ask.
- Action: Create a "customer advisory board" of your most critical (but constructive) users.
- Action: Make feedback easy. Are your support channels buried?
- Action: When you do implement feedback, shout it from the rooftops! "You asked, we listened. The dashboard now has X..." This closes the loop and builds intense loyalty.

Here’s an infographic for the whiteboard. This isn't just a "nice to have" cycle. In the modern economy, this is the new flywheel. It's how you build a brand that can't be easily copied by a cheaper, faster competitor.

1. What is inclusive marketing, really?
Inclusive marketing is the practice of creating marketing campaigns that reflect and resonate with the diverse identities of your audience. It's not just about images; it's about solving for different needs, perspectives, and pain points. At its best, it's about redefining your TAM by inviting in people who were previously ignored.
2. Isn't this just a B2C strategy? I'm in B2B.
Absolutely not. Your B2B buyer is still a human. Does your software's UI work for someone who is colorblind? Is your onboarding documentation available in multiple formats (video, text) for different learning styles? Do your case studies only feature one type of "ideal" customer? B2B is ripe for disruption through inclusivity.
3. How do I start "sustainability" if I'm a tiny, pre-revenue startup?
Start with your "People" and "Planet" commitments, as they're often free. "Planet" can be as simple as a remote-first policy to reduce commuting. "People" can be about building a transparent, respectful company culture. You don't need a massive budget to be authentic. Your business model is your sustainable practice.
4. What's the difference between authenticity and "purpose-washing"?
"Purpose-washing" is when a brand's stated values (e.g., "We support X") are not backed up by its actions (e.g., its internal policies, supply chain, or political donations contradict X). Authenticity is the alignment of saying and doing. It's about transparency, even when you mess up. See our playbook for more.
5. How long does it take to see an ROI on this?
This is the wrong question. This is a long-term strategy, not a short-term hack. The "ROI" is a resilient brand, a lower cost of acquisition (due to word-of-mouth), higher LTV (due to loyalty), and the ability to attract and retain top talent. You'll see "soft" metrics (like brand sentiment, community engagement) improve first, followed by the "hard" metrics (revenue, retention) as the flywheel spins up.
6. What is the 'Triple Bottom Line' (TBL)?
The TBL is a business framework that measures success not just by financial profit, but by three "P's": People (social impact, community, employee well-being), Planet (environmental impact, sustainability), and Profit (the traditional financial bottom line). The idea is that all three are interconnected. You can read more from HBS about it.
7. Where can I find a good guide to niche marketing?
The U.S. Small Business Administration (SBA) has fantastic, no-fluff guides on market research and defining your target market. It's the practical, "how-to" foundation for identifying the very "misfit" pain points we've been discussing.
The Takeaway: Stop Selling, Start Solving
I still haven't bought those swim trunks, by the way. I'm too busy thinking.
The biggest lesson from this deep dive is this: The sustainable and inclusive swimwear market is winning because it stopped selling a product and started solving a feeling. It solves the feeling of "I don't belong," "I'm not seen," and "I'm worried about the future."
As founders, marketers, and creators, that's our real job. It doesn't matter if you're selling code, creative services, or... swimsuits. The brands that make their customers feel seen, safe, and part of something real are the ones who are going to win the next decade. Everyone else is just treading water.
The water's warm. It's time to jump in.
So, my question for you is: What's one "misfit" pain point in your industry that everyone else is ignoring, but that you could solve this week?
