As a tourist with an eye for eco-friendly products, you have probably noticed that most swimwear is made from materials like nylon and polyester. However, there has been a move towards sustainable swimwear made of natural fibres such as cotton and hemp in the last few years.  

The list of benefits of this type of material is long: not only are they better for your skin but also the environment! So if you're looking to purchase some new sexy bikinis or one-pieces, I recommend checking out these brands that use sustainable materials in their garments.

    Ultimate List of Eco-Friendly Sustainable Swimwear, Melbourne Australia

    Bombshell Bay Swimwear - Sustainable Swimwear Melbourne

    Bombshell Bay Swimwear is an eco-friendly Melbourne label that designs and creates sustainable eco-luxe swimwear out of floating plastics and other misplaced synthetics sadly found in our oceans.

    We only use Italian Carvico Vita recycled fabric to ensure the highest quality of swimwear is produced. Carvico Vita is made with 78% Recycled Polyamide with 22% Elastane. Not only is our fabric known for helping clear our seas from plastics and ghost netting, but it also has key benefits such as Excellent UV Protection, pilling resistance, incredible shape retention, Resistance to sunscreen and oil and ultra-chlorine resistant too. Did we mention that it has 2-way stretch, and it's SUPER soft. The Italians defiantly know what they are doing, that's for sure.

    We have a small dedicated team; we like to call our magicians who create our swimwear offshore in beautiful Bali. By doing this, we only create small amounts of each collection, which makes them not only exclusive pieces but it also really allows us to be a truly sustainable swimwear brand. We are a small but proud Australian owned label helping to do our part in making our oceans a cleaner place for our marine life while we continue to make only the best quality swimsuits for you, our beautiful customers.

    Seapia - Sustainable Swimwear Melbourne

    Our Sustainable Way

    One of the biggest improvements in fashion these days is transparency and accountability – what price are we paying to look and feel good?

    From the labour used to make the product, the fabric that it's produced from, the distance it travels to reach us, and the packaging it comes in, there's usually a heavy price on the environment to make us feel good on the beach or in the pool.

    Our brand philosophy is that looking good in swimwear shouldn't be at the expense of the world. We can look and feel great in sustainable swimwear that is durable, that doesn't cost the Earth and reduces our carbon footprint.


    Seapia reflects the tropical style of Costa Rica, where the brand's founder Fiorella Castro was born. Fiorella's diverse fashion background and love of nature have given her a unique perspective on life, leading to this iconic range of swimwear with a Latin American heart and high tech, low-impact structure.

    So by using materials carefully selected for their low impact on the environment, we can give back to the world without compromising on beauty and style, which provides a unique and rewarding experience for the wearer. 

    Aquadiva - Sustainable Swimwear Melbourne

    Eco & Ethical

    Aquadiva takes inspiration from our favourite season, summer, and the essence of hot days, starry nights and the feeling of wanderlust. We aim to create swimwear that not only looks magical but feels magical to wear!

    The beauty of the natural world is also very inspiring to us, so it makes sense to look after it as best we can! Our environmentally conscious swimwear is not only designed to last and reduce the need for consumption but is produced with as little waste and environmental impact as possible. We are totally committed to running an environmentally and socially responsible business to ensure the health of our planet for future generations to come.

    Firstly, they have to be of the highest quality possible. We believe in slow fashion, not disposable swimwear! When you buy an item, you should be looking to make good use of it, not throw it away after a few swims. In fact, many of our customers have full collections of Aquadiva pieces from seasons past. 

    Recycling - Waste Not! 

    All of the waste products created in our manufacturing process are recycled. Even the inks that are used in the Aquadiva fabric printing process are earth and human-friendly. We also pay to have all waste paper taken to a recycling plant while scrap fabric is donated to local community projects. 

    100% Australian Made 

    When you buy Aquadiva, you are buying a product that reflects the hard work and passion of many talented Australians.  

    Our team of dedicated artists and craftspeople produce Aquadiva right here on the sunny Gold Coast, in Queensland - not in a foreign country. We believe in providing Australians with a means to live and prosper, not taking advantage of cheap labour in developing countries to maximise profits. Be wary of brands that produce cheap quality items and pocket the price difference - success should not be at the expense of others.  

    Eco-Friendly Sustainable Swimwear FAQs

    What Material Are Swimsuits Made Of

    The last thing you need in a swimwear fabric is your bikini or swimming shorts to turn see-through underwater. A fabric that shrinks when wet can also cause a few embarrassing problems.


    One thing you don't want in a swimwear fabric is anything too heavy. Lighter fabrics will look and feel like comfortable underwear. Most swim-quality material is made from lightweight synthetic fabrics. An ideal weight would be between 180-200g per square meter of material.

    Look and Feel

    Swimwear fabric needs to look good and help you feel confident. It should be soft, flexible, and have an attractive design or print. Let's face it. Most modern-day swimsuits leave little to the imagination. What's on show needs to look fantastic, so you don't feel anxious wearing the garment. The fabric should enhance your assets, not detract from them. Avoid neon colours if you are at all body-conscious.


    An uncomfortable swimming costume is going to hamper your enjoyment severely. As well as your freedom of movement. A swimwear fabric needs to be flexible enough to allow your body to move. It also needs to be soft enough to prevent rubbing and chaffing. When it comes to swimwear, the softer the material, the better.


    Everyone likes to look good at the beach or the side of the pool. Unfortunately, today's swimwear fabrics contain elastane, which is figure-hugging. Able to control and contain those areas of our bodies we'd all rather hide, the best swimwear material will make us look thinner with more of an athletic silhouette.

    Fibre Content

    When it comes to swimwear, the best fibre content for your fabric is stretchy synthetic. Created by blending either polyester or nylon with elastane, swimwear fabrics are naturally durable, water-resistant, and quick-drying. A polyester/elastane mix will also give protection from UV rays and be resistant to chlorine.


    The last thing you need is the colour from your swimsuit coming out in the pool. Ensure your fabric is colourfast before diving into the deep end. Materials known to fare badly when it comes to colour retention include nylon. Not only does it fade quickly, but any printing or ink on the material is also likely to bleed into the water. If you want a logo on your swimming shorts, play it safe and stick to polyester-based fabrics.


    Particularly important, if you are taking the plunge daily, you need a material to be quick-drying. There's nothing worse than having to carry a soggy swimsuit around with you after your morning swim. Most synthetic fibres have a water-resistant quality making them ideal for regular-use swimwear. They'll not only dry quickly but can also be rinsed out, dried, and ready for your next trip to the pool in no time.


    Swimsuits are designed to be close-fitting. The closer the fit, the less likely they'll accidentally fall off underwater. To be figure-hugging, the fabric has to be flexible and stretchy. Unfortunately, many swimwear is made with negative ease, meaning there isn't much space available when you're wearing it. Make sure your fabric has the necessary stretch to accommodate both you and your need to breathe. Try to find fabric with a four-way stretch with at least a 60-70% stretch in any direction.


    Swimwear fabric needs to be durable and resilient. It comes into contact with pool chemicals and UV rays, and both can cause degradation. A key element for any fabric used in swimsuits is the ability to resist damage caused by chlorine, sunshine, and other abrasive substances like sea salt.


    For a long-lasting, durable swimsuit, try to pick a fabric that contains anti-pilling properties. Nylon is known to pill over time as it lacks resistance to chlorine damage. The best fabric for resilience to harsh chemicals is polyester. If anti-pilling is important to you, choose a material with polyester content.

    Ease of Care

    Any time you have a fabric coming into regular contact with harmful chemicals like chlorine, you need to wash it. The great thing about synthetic fibres is they are easy to care for. A quick dip in a cool wash, followed by a drip-dry, is all it takes to get the smell of bleach out of your swimwear. So make sure your swimming fabric has a wash-and-go element built in.


    This is a hard box to tick when it comes to swimwear. The best fabrics are synthetics due to the resilience, durability, and flexibility inherent in the material. Unfortunately, synthetics are also the least sustainable of all fibres. Many are petroleum-based and rely heavily on fossil fuels. All is not lost, though. By considering recycled materials, you can go a long way to counteracting the environmental impact of your swimsuit.


    Fabric for swimwear can vary in price. The choice is down to your budget, from the inexpensive polyester-based materials to the slightly higher cost of a nylon garment. The ideal fabric for your swimwear should be the best quality you can afford. Ensure the material has longevity, and the investment you make in your swimsuit will repay you with a garment that will look good after multiple swims.

    The amount of fabric needed for a swimsuit depends on the style of suit you are making. There are a couple of things to consider when calculating material amounts. First, do you want to line your swimwear and a full suit or a two-piece bikini? For this example, let's make a bikini.

    Commercial swimwear is made with negative ease, meaning it's cut smaller than your measurements. This creates the tight-fitting, figure-hugging silhouette swimwear is known for. As a rule of thumb, it's normal for an amount of up to 2 inches to be deducted from your size. This figure will change depending on how tight you want your bikini.

    The next thing to do is measure your bust and hips and decide how much coverage you want. For example, do you want a low-cut top with tankini briefs? Or full bust coverage and low cut briefs?

    The actual fabric needed will be determined by your measurements, but between ½ to ¾ of a yard in a 60-inch wide fabric should be ample. Remember to purchase the same amount for your lining!

    When thinking of bathing suits, the one-piece swimsuit springs to mind. Because more of the body is covered, fabric needs for this option will be slightly higher than for bikinis, tankinis, and briefs.

    Bathing suits or one-piece swimsuits are made with negative ease. Measurements for the one-piece option will need to include coverage for your stomach and back. A yard of fabric measuring 60-inches wide should give you enough material for an all-in-one bathing suit.

    Our Approach

    The water women should wear Hakea. It's for people who enjoy the sting of salt, the cool ocean current on their hand's heel, and the warmth of the sun's rays. It's for those who appreciate the blessing of sunny mornings, long evenings, and free time in between.

    Hakea is for a way of life that enjoys leisure and exploration. Take a minute, an hour, or even a day to carefully peel an orange, sneak away to go surfing, or prepare a lavish supper to be enjoyed outside. Inhaling the moment with the shoulders dropped, eyes smiling and mind at ease - Hakea is for that state-of-being – most fleeting and precious – of feeling uninhibited and free.

    Australian desert and dry coasts served as inspiration. Our classic styles in earthy colour schemes are manufactured in small quantities, shifting the focus away from material acquisition and onto a connection to the things that really matter.

    SAINT SOMEBODY - Sustainable Swimwear Melbourne

    What's the Story?

    The first thing you notice about the pieces is the quality. You can see it and feel it. Seamless, ethically handmade swimwear that is flattering, comfortable and made to last. The fit is focused on women in the average size range with designs in sizes 12-22 to suit busts both small and large. 

    The label was founded in 2018 by Sophie Henderson-Smart, a mum and beach dweller from Manly Beach, Australia. Sophie, although falling in the majority' average size' category, would browse store after store both at home and abroad, searching for high-quality designer swimwear made specifically for her shape, but it was fruitless. As the summers went by, she became increasingly body-conscious and frustrated with the lack of options and eventually avoided the beach altogether. Sound familiar? This is the story for far too many women.


    SAINT SOMEBODY is a movement of body positivity with authenticity and purpose at its core. Quite simply, we exist to make the world better by gifting confidence to women with luxury swimwear designed for curves and through our global giving to people in need.    

    Less is more. We like to take it slow, ensuring quality is of the highest possible standard. Everything is finished by hand in small batches and designed to last. We care about the talented people who make our garments. They are part of our extended team and a significant part of our success. This is reflected in both conditions and pay.

    The Starting Point

    I started designing these one-of-a-kind prints in Photoshop one day in June 2014. I had the idea of having them printed and turned into swimwear.

    There weren't many companies at the time that printed and hand-sewed swimwear locally. We gained popularity, and as more and more clients started to know, enjoy, and trust our brand, I added a few more upscale seamstresses to the team.

    ZAZI SWIM - Sustainable Swimwear Melbourne

    Sustainability Made Sexy

    Our swimwear is constructed of ECONYL, a recycled nylon created from waste materials like fishing netts and other post-consumer goods.

    In order to preserve a luxurious feel while using less water and having a smaller environmental impact, our resort clothing is constructed from natural fibres like organic cotton and linens that are sustainably sourced.

     All of our packaging including garment bags are made from compostable and recycled materials so will break down in landfill and can go into your compost. We care deeply about the planet and creating a business that gives back to nature. That's why we're thrilled to share that we're partnering with One Tree Planted to plant a tree for every order.
