Why consider a sustainable bra?

Fast fashion already contributes to a huge chunk of the textile waste sent to our landfills. According to the Recycling Council of Ontario, 37 KG of textile waste per person ends up in Canadian landfills each year. Shopping for ethical and sustainable bras undergarments can surely help to minimize the amount of textile waste.

Not sure how to shop for a sustainable bra? Here's what to look for:

To shop for the best sustainable bra there are three main criteria to consider: the fabrics and the materials used, ethical sourcing, and corporate responsibility. These criteria cover both how natural resources are used and how the workers are treated as the intent is to embrace slow fashion while avoiding the worst fast fashion brands.

1. What Fabrics and materials is the company using?

Just as there are beauty care products that are not good for your skin, there are fabrics that are not good for the environment as much as your skin. As you begin to understand the difference between fabrics you then divert to sustainable fabrics such as organic bamboo, organic cotton, linen, and hemp, with certifications to verify the origins of these fabrics.

Synthetic fabrics like modal, TENCEL™, and lyocell are great when produced sustainably while plastic-based synthetic materials like nylon, polyester, or spandex are to be avoided because of their toxic components. 

A few of the best certifications include the Global Organic Textile Standard (GOTS), the Organic Content Standard (OCS), USDA-Certified Organic, the Recycled Claim Standard, the SCS Recycled Content Certification, the Better Cotton Standard, and OEKO-TEX® 100. 

2. How are the fabrics and materials sourced?

Ethical sourcing is the process of ensuring the materials being sourced are obtained in a responsible and sustainable way, that the workers involved in making them are safe and treated fairly and that environmental and social impacts are taken into account.

Certifications to look for are Fairtrade, B-Crop, WRAP, and BSCI. At times if the brand is smaller they don’t have immediate funds to get these certifications. If you are not sure, we suggest always asking questions for transparency.

3. What is the brand's corporate responsibility?

Looking at what else a given brand is doing in terms of social and environmental responsibility. This might include practices such as plastic-free packaging, social and environmental initiatives like carbon neutrality, and/or certifications like B-Corp.
