Best Fabric for Swimwear

Finding the ultimate swimwear is not just about the cut or colour; the secret lies in choosing the best fabric for swimwear. The truth is, the optimal material is the durable-yet-skin-friendly sort. It can make a world of difference in how you feel and look.

With so many options out there, how do you choose the perfect material?

We've delved deep into the world of swimwear fabrics, and here's what we've found. Join us as we unravel the best fabric options when it comes to swimsuits and bikinis!

What this article covers:

Choosing Swimwear Material: The Top Fabrics

When it comes to selecting the most flattering swimwear, the material is paramount. The fabric dictates how you'll look by the poolside, how you'll feel wearing it throughout the day, and how long the outfit will last.

Among the myriad of options, two fabrics have earned their place in the spotlight. Here are the frontrunners we selected:


Nylon stands as a favourite in the swimwear industry, prized for its versatile and resilient nature. Initially introduced as a synthetic replacement for silk, it quickly found its footing in various apparel, swimming costumes included, due to its multitude of beneficial properties​​.

One of nylon's primary advantages is its incredible strength. Based on our observations, it's a durable synthetic fabric, which means it stands up well to wear and tear.

You'll find that swimwear made from nylon, like the Collective High Neck swimsuit from Seafolly, retains its shape and quality even after numerous swims and sunbathing sessions​​.

Nylon also dries quickly, a feature anyone emerging from the pool or ocean will appreciate. Nobody likes the feeling of a soggy bathing suit, and nylon's low moisture absorbency ensures that you're not stuck in wet swimwear for long after a dip​.

What really makes nylon stand out as a favourite is how it pairs with other materials. While it's robust and flexible, it's often blended with elastane to introduce stretchability, ensuring a snug, flattering fit that accentuates body curves without feeling restrictive​.

Moreover, nylon's lightweight nature and ability to be dyed in a plethora of colours and patterns give designers the freedom to craft stunning, comfortable pieces that appeal to every style and preference.


Elastane is a synthetic fibre known for its exceptional elasticity. Our research indicates that it was invented in 1958 and revolutionized the fashion industry with its ability to stretch up to 500% of its original length and then return to its original shape.

This characteristic is particularly beneficial in swimwear, providing a body-hugging fit and freedom of movement, critical for comfort whether you're lounging by the pool or engaging in water sports.

Furthermore, elastane's resilience to body oils, perspiration, and cosmetics enhances the durability of swimwear.

The Antagonist Wide Shoulder swimsuit from Maryan Mehlhorn showcases these benefits beautifully!

What Else to Look for in Swimwear Fabric

Beyond the basic fabric type, other critical factors determine the quality and comfort of swimwear. Each aspect has a direct impact on the garment's performance and durability, as well as its environmental footprint.

The weight of the swimwear fabric affects its comfort and functionality. Lighter materials allow for better breathability and quicker drying but may be less durable. In contrast, heavier fabrics can offer more support and coverage but may retain more water and take longer to dry.


The composition refers to the blend of different fibres used in the fabric. Swimwear often combines materials like nylon and elastane to achieve the ideal balance of stretch, durability, and comfort. The specific blend can affect the garment's fit, support, and longevity.

Our findings show that a composition of 80-90% nylon combined with 10-20% elastane or Lycra is optimal.


Sustainability in swimwear fabric involves the use of eco-friendly materials and production processes. Options like recycled nylon as well as practices that reduce water and energy consumption are becoming increasingly popular.

Are Natural Fabrics Ideal For Swimwear?

In the discussion about what bikini bottoms are most flattering, those made from natural fabrics arise as a contender.

While natural fabrics have their benefits, they traditionally lack the elasticity found in synthetic counterparts. This shortfall means they might not conform to the body as snugly, potentially leading to a less precise fit and reduced range of motion in the water.

For avid swimmers or those seeking athletic swimwear, this could be a notable drawback. Thus, when opting for fabrics, it's important to consider your needs and how the garment's elasticity will impact your beach or poolside experience​.

In the quest for the ideal swimwear, considering fabric is paramount. Synthetics like nylon and elastane dominate due to their durability and flexibility, essential for any aquatic activity​. Other factors worth considering when deciding on the right fabric include the material's weight and composition.

But sustainability shouldn't be overlooked. Brands are embracing eco-friendly materials, ensuring we can enjoy the beach without compromising the planet​​.
