Returns due to incorrect sizing

MYSZ – MySize Inc.
“I am” in Basque — a celebration of individuality and our roots in the Basque Country.
“Naiz” sounds exactly like “nice” in English. Our goal: a perfect fit — for who you are and what your body is really like.
We physically test garments on focus groups with diverse body morphologies. A size chart alone cannot predict how a garment fits a real person.
Fit is a complex, body-specific problem. We do not approximate it with digital overlays on a flawed system — we solve it from the inside out.
From fit validation in pre-production to return analysis after launch, we cover every stage where size and fit decisions are made.
We do not deliver large volumes of raw data. We deliver clear, team-ready insights that product, ecommerce, and design teams can apply immediately.
Born from a simple but persistent observation: the fashion sizing system was broken, and no one was fixing it from within.
Naiz Fit joined MySize Inc., a global leader in AI-driven measurement solutions, strengthening our ability to scale size and fit intelligence in international fashion markets.
Working with fashion brands and retailers across Europe — reducing return rates, improving collection quality, and adapting garments to their customers’ real bodies.
At Naiz Fit, we started as an online size recommender focused on reducing returns in fashion ecommerce. Over time, we evolved into an advanced size and fit intelligence platform.
Having the courage to make decisions without fearing failure and the humility to acknowledge one’s own mistakes acting as the mini CEO of your area. It empowers us with speed and agility to find the hidden gems in the roughness of crazy ideas. No mistakes, no learning.
Group of different individuals forming a unified whole. Each team member places trust in the others. Spoiler alert: we consider fashion brands as part of our team. When we work together, we are stronger, we are better.
We confront challenges, celebrate victories, accept defeats, and always progress as a team. Because we believe that individual well-being is linked to performance and productivity, which in turn impact the collective. As social beings, we rely on each other.
We celebrate the uniqueness of each individual so that we are proud of who we are while making the world change and adapt to us, rather than the other way around. It allows everyone to be memorable for who they are without conforming to society’s standards.
A group of different people forming a unified whole — designers, engineers, data scientists, and fashion lovers who share the same obsession: making fit work for every body.
