Comfort that keeps up. 🌿

We made these breathable compression shorts and cushioned socks because they didn’t exist. Soft, comfortable and great for sport, school and everyday adventures - without relying on plastic.

The shorts are made with silky, moisture-managing lyocell to help reduce heat and chafing, while our socks contain 95% combed cotton for breathable comfort, cushioning and gentle compression.

Our cushioned, gently supportive socks are made with 95% combed cotton and just 5% elastane for stretch and light compression. No polyester. No nylon. No sweaty synthetic fabric.
We deliberately chose strong, long-fibre combed cotton to create a durable, breathable sock that feels comfortable through school days, sport and everyday adventures.

Why only two sizes? Because developing our own custom fabric required very high minimum orders. So we created two flexible size ranges designed to fit growing kids, teens and adults. And they’re cheaper than the polyester filled socks you’d find in Rebel 🙌

These aren’t ordinary cotton socks - and you won’t find them anywhere else. 💚

Our customers are absolute legends - and Jodie is certainly no exception. 💚

She sent us this video featuring one of our bestselling products, and we couldn’t love it more.

Jodie is also the founder of the incredible plastic-free kids’ mealtime brand Mindful Mealtime®️ which my own kids LOVE so please go and check out her beautiful products. And she has a giveaway going at the moment with a bunch of great prizes! (including a voucher from us Billie Green

As for our girls’ and women’s full briefs, their simple design is what makes them so comfortable. Instead of adding the usual polyester microfibre waistband, we fold over the soft fabric.

They may not last 500 years like their polyester rivals - but they’ll comfortably see you through a few good years, without creating centuries of unnecessary plastic waste. Made with certified GOTS organic cotton, they’re kinder against the skin and lighter on the planet.

Thank you, Jodie. We appreciate you - and every single member of our wonderful Billie Green community. 💚

Our boys don’t need plastic-wrapped compression to play sport.

They need something breathable, soft and comfortable that helps prevent chafing-without all the polyester and nylon.

That’s why we made our sports skins from TENCEL™ Lyocell. Still moisture-managing but without being a polyester/spandex blend. And at $34.95, they’re actually more affordable than most of the big brands.

Funny how choosing a better fabric doesn’t have to mean paying more.

We’re so excited to share that our Contour Clasp Bra has been selected as a Finalist in the Clean + Conscious Awards 2026 ✨💚

Anyone who knows me knows how much I care about the environment, ocean conservation and creating healthier, more sustainable basics for kids and teens - so recognition in the sustainability space always feels extra special.

As a small Australian brand, a lot of thought and care goes into every detail, from the design, the fabrics we choose right through to our plastic-free ethos across our business and supply chain, so we’re incredibly grateful to be recognised alongside so many inspiring brands.

A big thank you to for celebrating businesses working towards a healthier and more conscious future 🌿
