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 – and we can even say offered in sizes BELOW XS. Just any size out of the norm of XS-XL.
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 more size inclusive (it’s been hard to find several who go up to 5 or 6XL, but we’ve found a few). We’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 virgin 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. There aren’t many brands who use all natural materials for swimwear because they do not hold up as well in water.
The most commonly used materials in sustainable swimwear are:
- ECONYL: Regenerated Nylon
- rPET: Recycled Polyester
- Recycled polyamide yarn
- Recycled Cotton
- Plant-based fibers
