Silbon is a Spanish menswear brand known for its tailored aesthetic and strong online presence. As their ecommerce grew, so did their returns challenge.

Silbon partnered with Naiz Fit to implement a size recommendation tool built on the physical measurements of their actual garments, calibrated through focus group fit testing.

The results:

• Across 1.5 million unique visitor interactions: -65% in size-related return rate (from 20% down to 7% among users who followed the recommendation), 2.5x conversion uplift, and +18% average order value.
