This means that you are also laser-focused on finding the best ethical swimwear brands. 

Long gone are the days when chemical-laden, synthetic swimsuits were the only readily option. In 2023, there’s a plethora of affordable recycled swimwear, sustainable modest swimwear, sultry plus-size bathing suits, and many more styles made of good-for-the-planet materials.

We’re talking must-have one-pieces, two-pieces, tankinis, and monokinis in virtually every shape and size. Truth is that the swim sphere has come a very long way.

Some of the best sustainable swimwear brands even took it upon themselves to create multicolored and noir-hued surfing swimsuits ideal for adventurers. The latter was notoriously hard to find till recently. There’s an array of eco-friendly bathing suits equipped with SPF 50+ sun protection. 

Let’s not forget the slew of skirt suits and full coverage numbers that are available online!

We’ve laid out all the best straight-size and plus-size eco-friendly bathing suit brands for you’ll want to have on during all your sunshine-season shenanigans.

What is sustainable swimwear?

Sustainable swimwear is swimwear made using environmentally friendly materials and production methods, with a focus on reducing the negative impact of traditional swimwear manufacturing on the planet. 

This can include using recycled materials such as recycled polyester, and Recycled Nylon, as well as minimizing the use of harmful chemicals, dyes, and water during production. 

In addition, ethical swimwear may be designed to last longer than traditional swimwear, reducing the need for frequent replacement and ultimately reducing waste. Last, but not least, eco-friendly bathing suit brands prioritize ethical labor practices, ensuring that the workers who make the swimwear are paid fairly and work in safe conditions.

How does swimwear impact the environment?

Traditional swimwear is often made from virgin (non-recycled) nylon, polyester, and spandex, which are synthetic fibers derived from fossil fuels. The production of these materials can contribute to greenhouse gas emissions and environmental pollution. 

In addition, swimwear production often involves the use of harsh chemicals and dyes, which can be harmful to both the environment and human health. These substances can enter waterways and contribute to water pollution. 
On top of that, swimwear manufacturing requires water for various stages, such as dyeing, washing, and finishing. This can lead to water depletion and water pollution, as well as the release of untreated wastewater. Let’s not forget microfiber pollution. Synthetic fabrics like polyester and nylon release microfibers when washed, which can end up in waterways and harm aquatic life.

What is the most sustainable material for swimwear?

The most sustainable materials for swimwear are those that have a minimal impact on the environment, are recyclable or biodegradable, and can be produced in an eco-friendly manner. Recycled Polyester, Tencel, and Econyl are all great options.

Why is sustainable swimwear expensive?

Granted, sustainable swimwear can be more expensive than traditional options. Especially if you are used to paying 10$ per set – hello, fast fashion. Ethical swimwear is expensive, firstly, due to the use of eco-friendly materials, such as recycled nylon or polyester. These materials can be more expensive to produce and source than non-sustainable materials, which can drive up the cost. 

Then, you have to consider that many sustainable swimwear brands prioritize ethical labor practices, such as fair wages and safe working conditions for their workers. The money has to come from somewhere, right? Plus, eco-friendly bathing suit brands often produce in smaller quantities than mass-market swimwear brands. This is because they are committed to reducing waste and overproduction, which can result in higher production costs per item. 

Lastly, ethical companies focus on producing high-quality, durable products that will last longer than traditional swimwear. This means that, in the long run, your favorite eco-friendly pieces will actually save you money from constantly buying new styles.

How can I help my swimwear last longer?

  1. Rinse your swimwear in cold water after each use to remove any chlorine, salt, sand, or other debris that can damage the fabric.
  2. Hand wash or use a delicate cycle: Machine washing and drying can be harsh on swimwear, so it’s best to hand wash your swimwear or use a delicate cycle with mild eco-friendly laundry detergent.
  3. Hot water and bleach can weaken the fibers of your swimwear and cause the color to fade. Stick to cold water!
  4. Avoid sitting on rough surfaces like concrete or rough rocks, which can damage the fabric.
  5. Wringing or twisting your swimwear can stretch out the fabric and damage the shape. Instead, gently squeeze out excess water and lay it flat to dry.
  6. Store your swimwear flat or rolled up, rather than folded, to avoid creases or wrinkles that can be difficult to remove. Don’t store wet swimwear in a plastic bag, as this can cause mildew or odors.
