Sustainability is at the heart of all KARTINI designs - from materials and methods, to packaging and production style.


The textile industry leaves one of the largest water footprints on the planet -  as it consumes a substantial amount of water in its manufacturing processes, used mainly in dyeing and finishing processes. The wastewater from textile plants is classified as the most polluting of all the industrial sectors, considering the volume generated as well as the effluent composition. The increased demand for textile products, the increase in their production, and the use of synthetic dyes have together contributed to dye wastewater becoming one of the most significant sources of pollution to the world's waterways. 

The industry's challenge is to adopt more water-friendly technologies. Enter sublimation dyeing - an environmentally conscious design process that is 100% waterless and low waste.

We use sublimation dyeing for all our patterned swimwear designs.

In this method, heat-activated dyes are used to transfer prints from the source to textile by the process of sublimation. Sublimation basically refers to the passage of molecules from the solid to gas state, without moving through a liquid state. During the printing process, heat is applied to sublimation dyes, to directly convert them into gaseous form. Simultaneously, the dye makes contact with a material, like elastane. Upon exposure to heat, the cloth fibres open, allowing the dyes to permeate into the fibre and bond with it permanently. The prints are therefore transferred from the source to the textile. All that is needed to permanently fix the colour is heat.The result? One of a kind prints that do not fade, minimal waste and no harm done to our waterways!


Billions of plastic bottles go into landfills every year. But now you can do something about it.

We create all our Swimwear, Activewear and Swim Intimates ranges using REPREVE or ECORIB.

REPREVE is amazing! REPREVE transforms recycled bottles into a premium fiber, specifically designed to make swimwear and athletic apparel. Their process embeds properties like wicking, adaptive warming and cooling, water repellency, and more at the fiber level.
ECORIB is a beautiful, premium textured swimwear fabric which is made from 87% recycled polyester - and believe us, there is a lot of polyester that needs recycling!

As a consumer, you can make a difference by choosing labels that use sustainable materials like REPREVE or ECORIB to create quality garments that last. Say no to fast fashion!


All our designs come packaged in 100% cotton, reusable drawstring or tote bags, depending on the size of your order.
We include these bags in your order as a beautiful alternative to plastic packaging, and because we know just how useful they are! Use the drawstring bags to keep your swimwear organised in your drawers, and use the tote-bags when you head to the beach or to pick up your groceries.


We make-to-order every single piece purchased through our online boutique or by our gorgeous stockists. 

By managing our orders this way, we eliminate over production and the need to reduce the price of stock to make space simply for the sake of new designs. This means we do not participate in mass sales.

Although this goes against the grain of our industry we are proud to be part of a slower and more sustainable movement where we create quality, timeless pieces that will last you a long time. 

 There is a short wait time while we lovingly hand craft your swimwear, intimates or activewear. When customers place an order, they are choosing to shop mindfully while actively supporting an independent, sustainable brand.
