Can I wash my WONDA bikini in the washing mashine?

Yes, you can wash it at 30° (no hotter). However, we recommend you to predominantly hand wash it and not to wash it in the washing machine too often.

What is the fabric of the bikinis made of?

We use an eco-sustainable techno-woven fabric called Carvico. 78% of the fabric is regenerated nylon which means that it’s fully recycled from plastic waste. The yarn comes from a company called Aquafil which uses a unique process to process old plastic waste into new nylon. They collect plastic waste from the ocean as well as from landfills, sort it and then regenerate it. The other 22% is Elastane which is necessary for swimwear as it gives the needed permanent elasticity which is required.

Carvico is high-quality fabric and has the following features:

  • Ultra chlorine resistant
  • Sunscreen and oil resistant
  • Muscle control
  • Shape retention
  • UV protection
  • Excellent coverage
  • Soft
  • Two way stretch
  • Pilling resistant
  • Perfect fit
  • Extra comfort

Where is my WONDA bikini made?

The factory that produces our WONDA bikinis is located in Lisbon in Portugal – very close to our Lisbon office. The factory is very small and only produces for a few smaller swimwear brands. We are visiting the factory every week to always be sure that everything is going well and that the gorgeous ladies who are sewing our products are happy.

All our bikinis are made with a lot of love and dedication. Therefore the production takes a little bit more time compared to what you might be used to from other fashion companies. Fair and ethical production takes its time. However, we always make sure that we have a case stock available for you, but we will probably not be able to always have all our models in stock. In this case, you might just need to wait a little bit, however, there is one thing you can be sure about: the patience will pay off.

What if my WONDA bikini is broken or doesn't fit me anymore?

The beauty of the fabric our WONDA bikinis are made of is not only that it’s recycled but also recyclable infinitely without ever losing its quality. We want to make use of this amazing opportunity to further minimize the impact our business has on the environment. In case of damage or if at some point your WONDA bikini doesn’t fit you anymore, we are currently working on implementing a return and recycling program.
