About us

About us
We're so happy you're interested in learning more about our brand! We're Simone and Joyce, and we've been running our jewellery brand MIAB Jewels together for many years. We've had the chance to explore some amazing places, like Hong Kong islands, Bali, Thailand, and many European sun destinations. It was on one of these trips that we had the idea to create fair swimwear. Our ECO-friendly fabrics are designed with comfort and convenience in mind. This is also how our idea for Billie the brand came about! On our website, you will also find a number of our iconic jewellery pieces that match perfectly with our swimwear. We also love the coast in the Netherlands, we enjoy living and doing business in The Hague. There's a good chance you'll see us in a Billie the brand outfit in the summer! And the name? It's named after our very first (grumpy) fluffy office cat – Billy. And there was Billie the brand, sun worshippers to cool surf girls – we've got you covered!

Female designers
All bikinis are designed by our team of female designers, who understand what women want and need in their swimwear.

Comfortable fit
Our bikinis are designed with comfort in mind, with soft ECO fabrics and thoughtful cuts to ensure every woman feels confident and comfortable, regardless of body type.

Durable materials
We are passionate about sustainability and use eco-friendly materials, such as recycled fabrics, to reduce our impact on the environment. In the spring of 2022, we came up with the idea for our bikini brand and it was launched at the beginning of 2024. This mainly involves quality control of the materials and finding a good supplier. We are thrilled to be launching a brand with recycled materials! We are proud to say that our swimwear is made of 82% recycled material and 18% elastane!

Ethical Production
We are proud to say that our bikinis are ethically produced in factories with fair working conditions. We are passionate about having a positive impact on both the planet and the people involved in all processes. We have close, personal contact and work with regular suppliers and contact persons so that we can guarantee this process.

Inclusivity
Our brand is all about embracing diversity and inclusivity! We offer a wide range of sizes and styles so every woman can find the perfect bikini that suits her.
Modular Designs: We know that women have different preferences, so we offer modular designs that allow customers to create their own bikini based on their style and needs.

Transparency
We believe in transparency about our production processes, materials and supply chain. Customers can easily find information about how our bikinis are made.

Long lifespan
We are thrilled to combine the finest materials with our unparalleled craftsmanship to create bikinis that are not only gorgeous but also long-lasting and resistant to wear and tear. This means you can enjoy your bikini for longer, reducing the need for frequent replacement.

Zero-Waste Packaging
We're proud to say that our packaging is eco-friendly and designed with minimal waste. We avoid excessive packaging material and encourage customers to consciously deal with packaging waste. Our shipping bags are made from 90% recycled plastic, which is a thin but strong material that means fewer raw materials are needed. These bags can be separated from the plastic waste, so they can be recycled again and again!

Double-sided design
Our bikinis are designed on both sides, so by purchasing 1 bikini you invest in 2 new looks. This innovative design increases the versatility of each bikini and gives customers two stylish options in one, making it easy to adapt their personal style to different occasions.
