The Best Size Inclusive Swimwear brands that are also Sustainable!

With summer right around the corner, you may be looking for a new sustainable swimsuit. Swimsuits should make us feel confident and comfortable. They should be made to fit our bodies - not the other way around. Unfortunately, many sustainable swimwear companies don’t offer inclusive sizing. This makes it incredibly difficult for women of all shapes and sizes to shop sustainably. That’s why we’re here to help. Below, I’ve put together ten fantastic, size inclusive swimwear brands you’ll love.

What Makes Swimwear Size Inclusive? 

Size inclusive swimwear is simply swimwear that goes beyond straight sizes. This means the swimsuit is offered in sizes above XL or a women’s size 14/16. 

If a swimwear brand is size inclusive, they aren’t making a separate “plus-size” line. They simply offer all of their products in a wider range of sizes. This ensures that most bodies have access to the same styles, fits, and coverage - no matter their size.

All of the brands included in this article are size inclusive. I’ve also chosen brands that offer a range of price points to ensure that there are accessible options available. 

What Should You Look For In Sustainable Swimwear? 

When it comes to figuring out if a swimwear company is indeed sustainable, there are a few things you should look out for. Sustainable brands will use ethical labor, sustainable production methods, and eco-friendly materials. 

So what exactly makes a fabric sustainable? Sustainable swimwear can be made from a variety of eco-friendly fabrics, but they are typically made using recycled materials. Most sustainable swimwear will still have a small percentage of synthetic fibers. The majority of materials used, however, should be from recycled, regenerated, or natural sources. Sustainable companies should note what fabrics and fibers they use. 

The most commonly used materials in sustainable swimwear are:
