This bra is the most comfortable crop top I've ever worn. It is so smooth and feels like a second skin. There's no stitching and seams like other crops.

Our Innovative Fabrics (better than cotton)
We use innovative, nature-based fabrics like Lenzing™ Lyocell, Lenzing™ Modal, and organic cotton - produced in closed-loop systems and certified to the highest sustainability standards, including OEKO-TEX® 100. That means no harmful chemicals, no toxins - just skin-safe comfort.
Unlike polyester and nylon, which are 100% fossil-fuel-based plastics that shed microplastics into your body and the ocean, our fabrics are naturally breathable, bacteria-resistant, and cool against the skin. No heat and odour-trapping synthetics - just better for you and the planet.

Buying Your Child’s First Bra When They Have Sensitive Skin
Our Journey: From Nature to Nurture
From Nature to Nurture is the story behind Billie Green: why a child’s first bra shouldn’t come wrapped in plastic. After discovering plastics in everyday underwear, we created soft, breathable first bras and briefs for tweens & teens using Lenzing™ TENCEL™ Lyocell/Modal and organic cotton - OEKO-TEX® Standard 100 certified, with no polyester, nylon or padding. Adjustable designs that grow with young bodies, reduce washing, and put comfort, skin health, and sustainability first.
Buying Your First Bra
At Billie Green, we believe your first bra should feel like a second skin—soft, gentle and never itchy. Look for natural, breathable fabrics (like TENCEL™ or organic cotton) that are kind to sensitive skin. Avoid synthetic fabrics like polyester and nylon that can trap heat and cause irritation. Here are some great options for when your just getting started - and the best news is that they are designed to grow with you.
