Hi! I'm Caroline
I'm a mum of 3 based on the NSW South Coast and I started Billie Green after noticing how much plastic was in the products our young people are wearing. Big brands are charging consumers insane prices for cheaply made products that have fabrics derived from 100% fossil fuels. These petrochemicals form plastics that leach microplastics into our bodies and the ocean.
Research from leading universities both here and abroad and organisations like the Minderoo Foundation, is increasingly showing the harm that is being caused.
I have been working the last 2 years with leading bra designers and technicians to bring you the best fabrics with sustainable, interchangeable designs that grow with our young people.
I also run an award-winning sustainable eyewear brand called Ozeano.

Our Mission
At Billie Green, your wellbeing - and the well‑being of the planet - comes first. We believe that each young person deserves undergarments that are comfortable, safe, and feel‑good to wear. We’re committed to making the journey into finding that first bra and beyond, simple, honest, and empowering.
The intimate apparel and active wear industry is saturated with unnecessary plastics, toxic dyes and polyurethane foam padding. It's harmful to our health and the ocean. So we're here to change that!
Our brand is rooted in a passion for sustainability and a strong belief in better alternatives: better materials, better design, and better confidence for young people.

Why Choose Us?
Because we actually care.
We have been working for years to source incredible next gen fabrics that give you the performance you want for intimates (moisture-wicking, breathability and anti-bacterial) without the heat-trapping, toxic synthetics. These fabrics are even better than cotton in hot climates, because cotton holds moisture.
We believe we're the first brand for young people using these fabrics and we're doing our best to keep the costs affordable. Please help us out by letting your friends know about us! The more customers we can acquire, the lower our prices can go!
Our products are designed to grow with you - so you don't need to purchase every few months (our young people grow quickly!)
We don't pretend to be perfect and we'd love your feedback on how we can improve. Please email us at info@billiegreen.com.au or DM us on Instagram
