Girlfriend Collective

They are Earth’s #1 fan, so being eco-friendly is their top priority. Instead of filling the landfills with plastic waste, GF Collective collects and recycles it into a sustainable swimsuit that you will fall in love with! The textile is recycled in Taiwan and then cut and sewn in their SA8000 certified factory in Vietnam. What’s great about them is that they take back used Girlfriend apparel and recycle it again into new apparel. This brand also donates to #blacklivesmatter.

The amazing fact about Summersalt is the fact that their sustainable swimsuits are made of a fishing net that has been pulled out of the ocean.

Our next sustainable summer swimsuits are from the ever-famous Reformation. This brand imposes sustainability as its core in all that they do by investing in green building infrastructure to minimize their waste, water, and energy footprint. Using low-impact materials, rescued deadstock fabrics, repurposed vintage clothing, and recycling plastic bottles, you’ll find their sustainable swimsuits to be not only high quality and gorgeous, but also ethically made. If you really want to know how sustainable their products are, they have Refscale to track environmental impact and you can check their sustainability report. As they say, being naked is the #1 sustainable option, they are #2.

You may remember Patagonia from my sustainable dresses blog – I have a major crush on this brand. Yes, it is absolutely my go-to brand, and guess what? They also have sustainable swimsuits that you can show off this summer. When shopping for swimsuits with them you can choose from different categories like the materials and processes where there are two subcategories: recycled and fair trade. Most of their materials are recycled and 82% of their line are Fair Trade Certified sewn. As for their progress, they are investing in regenerative organic practices that improve soil health and reduce greenhouse gas emissions. I find their swimsuits to be extremely durable and able to withstand all the summer adventures.

This brand is born in France with the concept of designing high-quality and perfectly cut pieces that can be worn for a long time. Sezane’s sustainable swimsuits are made of eco-friendly materials and fit like a dream. Most of their items are produced in Europe, the rest all over the world depending on the origin of raw materials, expertise, working conditions, and production capacities. They have an atelier in Portugal, which is committed to sustainability; India, where they do embroidery by hand; Italy, for artisanal tradition; China, for their expertise in silk and Bulgaria for their excellence in threading and weaving.

News Splash: These sustainable swimsuits are made of recycled materials! Boden, one of my favorite slow fashion brands, use nylon made from 100% post-industrial waste materials which melt down using a chemical-free process. For quality control, they make sure that the swimsuit doesn’t shrink and the threads stay threaded. What I love about them is that they have “Mini Mission” which is a home activity for kids to keep their creative juices flowing. All packages are packed with recyclable materials.

Because of their mission to be plastic-free, the packaging of their product is made from recyclable material and is also biodegradable. As a swimwear company, they donate part of their sales to organizations that protect the ocean.

Last on our list is Londre. Founded by a best friend duo, they were inspired to design the most flattering and sustainable swimsuit that will last for decades. They used recycled plastic bottles found on the beach and streets and all water used in the recycling process is reused.
