There are a few key things to look for when choosing a sustainable bra:
-
Materials: Sustainable materials like organic cotton, bamboo and Tencel often use less water and are kinder on the planet.
-
Chemicals: Ideally, look for an OEKO-TEX certified brand, which means they don’t use toxic chemicals in their dyes.
-
Worker treatment: Look for brands that are transparent about their supply chain and factories.
