Fashion has a complicated relationship with plastic. As much as we pass laws to reduce it and march in the streets to get it out of our oceans, plastic fashion (like PVC shoes, clothes, and accessories) continues to be one of the industry's biggest trends. It's a funny paradox where our fascination with transparent pieces is subverting the actual transparency that we need from big brands. But what if we used the demand for this trend as a way to reduce our plastic problem?
The word "sustainable" was once tied to an underground and overpriced market. Now that the eco-fashion revolution is in full swing, there are tons of fresh brands like Mara Hoffman, Reformation, and Chromat that are gaining loyal fan bases while influencing mega retailers, like H&M and Zara, to follow suit. Our favourite part of the eco-fashion revolution? The many sexy sustainable swimwear brands that are made out of ocean plastic or postconsumer materials.
Chromat's fully edible bikini made out of seaweed definitely shook up the industry last Summer, inspiring other independent labels to step up their game. Now, swimwear brands like Ode & Rae, Marble Swimwear, and Weekday (to name a few) will have you looking sexy on the sand while saving the planet. Double win. Read ahead for our favourite environmentally friendly bikinis and one-pieces for all of your scantily clad Summer adventures.
