This month, the team at Peony Swimwear announce a very exciting global launch. The launch of a new category, one that pushes the boundaries in sustainability, impact on the environment and another addition to the peony experience. Introducing ‘Soiree,’ the collection that celebrates the global launch of sustainable Resortwear and Swim,  for the ultimate Peony experience. The collection is beautifully named to align with the meaning:

A Soiree is a special gathering for conversation and celebration. In conversation, we exchange thoughts and ideas, and we believe it has never been more important for us to share what we believe in and why.” – Peony Swimwear

The Peony team cares deeply for the environment and community. Their sustainability journey has been a long process; one that will never stop with constant innovation and progression.

We are acutely aware of the impact the fashion industry has on planet and its people, and we are passionately committed to driving change.

We believe in conscious creation and strive to deliver collections that pioneer sustainability. Inch by inch and seam by seam, we are pushing the boundaries of what is possible to bring you thoughtful pieces that are equal parts beauty, heart and substance.

We refer to this process as a journey because as we progress down this path to sustainability, we realise there is always more to learn, new ways to adapt and endless possibilities to evolve.

Each season we introduce new sustainable processes and become more efficient at minimising our impact. In all aspects of business, we constantly try to make improvements to do better. Our journey toward sustainability as an open and honest conversation with our suppliers, retailers, and most importantly, our customers.”

So what does this mean?

At Del Rainbow, we believe that education surrounding sustainability is integral. As a team, we are curious. We want transparency to ensure customers truly understand what sustainability means within a brand. Here is a breakdown of the Peony ‘Soiree’ Sustainability attributes and Impact. It is important to know what you are buying, who your makers are, and the impact this has on the environment.

Resortwear Materials

For our debut Resortwear collection, we have carefully selected fabrications that marry luxury with sustainability.

EcoVeroTM: EcoVeroTM fibres are derived from wood pulp sourced from certified sustainable sources. This innovative fabric is certified eco-responsible with the internationally recognised EU Ecolabel, a stamp of environmental excellence only awarded to fabrics which have a significantly lower environmental impact throughout their lifecycle: from raw material extraction to production, distribution and disposal.

Hemp: Hemp grows quickly and nourishes the soil it is grown in, reducing the need for fertilisers and pesticides. Hemp is naturally resistant to pests and needs little water. Hemp products can be recycled, re-used, and are biodegradable.

Linen: Linen is one of the most biodegradable fabrics in fashion history. It is strong, naturally moth resistant, and made from flax plant fibres, so it is biodegradable. There is very little waste in the farming of flax, as other parts of the plant, like the seeds, can be used for different products (e.g. flax oil). The durability of linen means this fabric is long-lasting. Linen softens with every wash and is more beautiful with each wear.

Recycled Polyester: Unlike regular polyester which is made from non-renewable petroleum oil which is a significant contributor to global warming, recycled polyester is made
by regenerating post-consumer goods that are already in existence. This significantly reduces the carbon footprint of the fabric and greatly saves the earth’s precious resources.

Organic Cotton: Organic cotton uses less water, less chemicals than non-organic cotton and only natural fertilisers in the farming process. Organic cotton crops aren’t treated with pesticides, insecticides, herbicides. This fabric has a significantly reduced environmental impact.

Swimwear Materials 

From design to composition and texture, all Peony fabrics are beautifully different, but the one thing they have in common is that they are all made from a high proportion of recycled content. This includes our custom textures, printed fabrics and inner linings, and it is the result of extensive in-house development. Most of Peony fabrics contain upwards of 90% recycled content. The percentage of recycled content is largely dependant on the design and structure of the fabric.

So, what does this actually mean?

In short, regular nylon is made from non-renewable petroleum oil which is a significant contributor to global warming. Recycled nylon differs from this because it is made by regenerating nylon goods that are already in existence, thus significantly reducing the carbon footprint of the fabric and saving the earth’s precious resources.

The Regeneration Process 

To make recycled nylon, post-consumer nylon goods such as old carpets, upholstery or abandoned fishing nets, and are collected through various initiatives worldwide.

This “nylon waste” is then regenerated through a depolymerization process that returns it to its virgin form. The regenerated nylon is then transformed into textile yarn and woven into fabric.

It is important to note that the quality of the regenerated nylon fabric is not compromised during this process. In fact, the nylon waste is recycled right back to its original purity meaning it is exactly the same as virgin nylon. The nylon can be regenerated infinitely, without ever losing its quality.

The end result is a beautiful high-quality fabric made from recycled content.

As the nylon yarn is not created from new, it results in the use of fewer resources and a significantly reduced carbon footprint for the final fabric.

We use compostable and biodegradable packaging throughout our entire supply chain for both swimwear and resortwear. Our bags are made from plant-based materials like cornstarch and wheat as opposed to petroleum. They break down easily and can even be placed in your compost bin. Due to trade regulations, we are required to ship all garments in bags. By using bags that are compostable and biodegradable, we save thousands of single-use plastic bags from entering the environment annually.


We work to minimise the negative impacts associated with manufacturing and to ensure that all people involved are treated fairly and respectfully along the way. Our supplier is certified SA8000 approved. SA8000 is the leading social certification standard for factories and organisations across the globe. This certification ensures ethical and fair compliance regarding child labour, forced or compulsory labour, health, and safety, freedom of association and right to collective bargaining, discrimination, disciplinary practices, working hours, remuneration and management systems.

Cleaning Oceans

We believe that every choice we make has an impact, and every impact, big or small, creates ripples. When you choose peony swimwear styles made from recycled nylon “waste”, rather than swimwear made from new nylon, you are helping to clean oceans, clear landfills and re-use nylon waste. Your choice results in reduced carbon emissions and greatly saves the earth’s precious resources. We are proud to use ECONYL® for all our printed styles. Did you know that the use of ECONYL® reduces the global warming impact of nylon by up to 80% compared to material made from non-renewable petroleum oil? The impact is significant and we are proud to be a small part of it, with thanks to you. As for our custom textured fabrics, we are working hard to quantify the impact of these and look forward to sharing this information with you in coming seasons. To learn more, we encourage you to visit the peony sustainability page, click here. We also recommend taking the time to visit the ECONLY, ECO VERO and REPREVE sites. Knowledge is power, sustainability is no longer a choice, it is a necessity. When purchasing, do so wisely and shop consciously. There is no compromise to luxury by purchasing sustainability with peony.

We hope that you love learning about Peony’s process as much as we do.
