About us
MAIN Design stands for sustainable, stylish and functional swimwear for women and children. Find out more about our history, values and our team - and what drives us to design swimwear that feels good and lasts a long time.
Our story
Our journey began in 2006 in Bali - a place known not only for its beautiful beaches but also for its lively surfing culture. Year after year, our founder Tiina went there to learn to surf and enjoy life by the sea. But behind the perfect social media images lies another reality: Depending on the season, many beaches are flooded with garbage. This sad experience moved us deeply and motivated us to use recycled materials. Tiina often collected plastic on the beach with her daughter - a small gesture to convey her environmental awareness.
Inspired by the challenge of finding the perfect surf bikini that doesn't get lost after the first wave, doesn't cut in, feels good, is feminine and is made of sustainable materials, the idea for MAIN Design was born in 2013. The name MAIN has a double meaning: In Indonesian, "Main" means "to play", and in English it stands for "mainly" - exactly what our brand stands for: functionality and fun on the water.
In 2018, a creative hobby became a company when Yvi joined us. Life had also changed - we both became mothers and developed a new vision: swimwear that not only brings joy to us, but also to our kids and is perfectly coordinated with the women's collection for the coolest mini-me look on the beach.
In 2020, we decided to become self-employed - we founded MAIN Design GmbH on a park bench in Zurich while the children were playing. Today, MAIN Design stands for long-lasting, sustainable swimwear for women who value freedom, adventure and quality.
From the sketch to the finished bikini
Every bikini starts with an idea. We draw, test and refine until we are happy with the samples. Our aim is to offer you pieces that not only suit your body, but also your values and lifestyle. Our designs are created in Switzerland, where we focus on quality, functionality and aesthetics and manufactured in Bali under fair working conditions from recycled materials and with a lot of love.
Our values
- Sustainability: Our bikinis and swimsuits are made from recycled fabrics (ECONYL®, Repreve®) We avoid overproduction through limited collections. Upcycling of fabric scraps (for accessories such as hair ties and children's hats and new samples)
- Fairness: Our production in Bali takes place under fair conditions
- Commitment: With every online purchase we donate 1% to Healthy Seas to protect the oceans
Swimwear for every woman
We celebrate women of all shapes and sizes. And we want to encourage women to feel confident and beautiful whether they're catching waves or relaxing at the beach or pool. With our Mix and Match feature you can customize your bikini to suit your body and needs - for maximum comfort and style. Our MAIN Mini children's collection offers sustainable, functional swimwear with UPF50+ sun protection and is perfectly color coordinated with the women's collection.
From mothers to mothers
As moms and entrepreneurs, we know how valuable long-lasting, well-thought-out products are. We know the balancing act between business, being a mom and me time. MAIN Design is our own adventure – characterized by passion, friendship and love of the sea.
MAIN Design is more than a brand – it is a movement for women who value freedom, adventure and sustainability. Follow us on Instagram and share your beach moments. Together we can protect the environment and inspire others to live sustainably.
Thank you for supporting us and growing with us.
All the best, Tiina & Yvi
Tiina Kosonen
Founder/designer
Tiina combines design, sustainability and functionality in every piece from MAIN Design. With a bachelor's degree in visual communication (ZHdK) and a certificate as a social media online marketing manager (WISS), she not only brings creativity but also strategic flair. Her love for aesthetics, order and balance is reflected in her designs. Her path to self-acceptance was not always easy: “I never used to be happy with my figure. Today I ask myself, why?” This insight motivates her to encourage women to feel comfortable in their skin - a message that is reflected in every collection. As a single mother, she masters the balancing act between creativity, business management and family life. Her passion for Rubik’s Cubes shows her ambition to learn new things and overcome challenges every day. Mostly with a coffee in hand ;)
Yvi Böni
Co-owner / Sales Rep
Yvi holds the business part of MAIN Design together. After her commercial training with a vocational baccalaureate in Buchs (SG), she completed a diploma at the IST Zurich (Higher Technical School for Tourism). As a mother of two, she knows only too well the balancing act between family, job and time for herself. That's exactly why sustainable, long-lasting fashion for women and children is particularly important to her - because she knows how important it is to have clothing that not only looks beautiful, but is also functional, comfortable and suitable for everyday use. Her heart beats for sport, nature and balance - as a certified yoga teacher, she lives exactly what MAIN Design embodies: lightness, self-confidence and an awareness of sustainability. Since 2018, she has been fully committed to the growth of MAIN Design - be it in direct contact with customers, in the organization or when testing new products.
