About Näz

100% Made in Portugal, and 100% committed to reducing the environmental impact of fashion.

How do they do it? By recycling surpluses, choosing only organic certified materials and operating a zero-km supply chain, which means small-scale, family-owned factories in the center and northern part of Portugal.

We make fashion look good, not only on you, but on the planet too.”

Founded in 2016, Näz collections can be found online and in more than 26 concept stores across Europe.


The main focus for Näz was to provide customers with accurate size recommendations. After a few months using Sizefox, they can now report a steady increase in conversion rates and a decrease in return rates of 2%.

The Challenge

The initiator of the project is Marta Ferreira, Marketing Specialist at Näz. She explains that the main goal was to offer their customers a simplified way to understand which size would fit them better, therefore giving them more confidence in purchasing. At the same time, the Näz team also wanted to reduce the time spent in answering customer requests related to sizing.

“We’ve been receiving feedback from repeat customers that the size guide is super helpful.” – Marta Ferreira, Marketing Specialist at Näz

The Solution

After a smooth and quick implementation, Näz went live with the widget and moved to the testing phase.

The results of the testing phase have been impressive: Sizefox helped Näz reduce returns by 2%, while helping them increase their conversion rates and lowering the time-to-conversion.

“We were so happy to hear about the free size guide app Sizefox! As a small brand, we were so happy to use this feature. The customer success team was always there when we had any questions.

The integration is really seamless, fast and reliable.”
