Hook:
Choose happy, not a size.

A phrase we whisper to ourselves again and again – in front of the mirror, in a bikini, in life. Because true self-confidence doesn't come from "fitting in" to something, but from feeling comfortable in your own skin. And that's precisely where sustainability begins.

MAIN Design sustainable surf bikini made from Econyl® – designed for confidence and comfort.

Real women, real summers – with MAIN Design 💙

Body positivity x sustainability

When we started MAIN Design , we thought we would simply design sustainable surf bikinis. But actually, we've built something deeper – a place where women can feel seen, authentic, and beautiful.

Sustainability isn't just about what you buy, but why you buy it. Choosing things that last – ethically produced, timelessly beautiful, good for you and the planet – is an act of self-love . 💚

Those who love themselves stop buying things to "fix" themselves – and begin wearing pieces that reflect who they already are: enough. This subtle shift – from "Does this suit me?" to "I feel good in it." – makes self-confidence a quiet form of sustainability.

Feel good first. Style follows.

Real Women, Real Summers

Our favorite photoshoots aren't photoshoots at all. They're real moments with friends, clients, mothers – women who surf, laugh, chase after their kids, live. Unfiltered. Unretouched. Simply real, confident, and beautiful .

"It's not about looking perfect. It's about feeling free again." – Anna
"For the first time, I wasn't thinking about my body while surfing. I was simply in the flow." – Lara from Zurich

Real women, real summers – that's you.

The Ripple Effect – Small decisions, big impact

Sometimes sustainability seems like a ripple that's too big a wave to take in. But every wave starts with a small movement. When you choose a MAIN Design surf bikini made from Econyl® , you're choosing more than just recycled materials. You're choosing mindfulness. You're choosing self-love. You're choosing what you want to support.

  • Less waste 🌍
  • More awareness 🌸
  • More mutual support 🤍

Every choice is a ripple. 🌊

💙 Join the Movement – ​​Be Part of the MAIN Reason

We believe every woman deserves to feel strong, free, and beautiful in her own skin – in the water, on the beach, and in everyday life. That's why at MAIN Design we design for real bodies , real moments , and real change .

Shop consciously → Wear proudly

Takeaway: Your identity is a sustainability factor.

When you choose to be yourself—confident, imperfect, authentic—you make a statement that transcends yourself. Every act of self-love is also an act of sustainability. Next time you slip into your bikini: You're not just wearing fashion. You're wearing an attitude.
