how Faslet’s virtual try-on reduced returns by 13.1% and boosted conversion for DIDI

In this case study, we explore how Faslet’s virtual try-on technology helped DIDI achieve measurable results by letting shoppers visualise how a garment looks on a body like theirs. We measured the impact of offering this experience through an A/B test to understand the outcomes on return rates and conversion for online shoppers on the DIDI website.

the challenge

Like many fashion e-commerce players, DIDI faced a persistent challenge: shoppers ordering items without the confidence that a garment would actually suit them. This uncertainty leads to a common pattern — buying to try, rather than buying to keep. The result is elevated return rates, increased operational pressure, and a less satisfying customer experience. DIDI sought a solution that would help shoppers make more informed, confident decisions at the moment of purchase.

the approach

To measure the real impact of virtual try-on, we conducted a controlled A/B test with DIDI. Online shoppers were split into two groups: one group had access to Faslet’s virtual try-on feature, allowing them to see how a garment looked on a body similar to their own. The other group had no access to the feature and followed the standard shopping journey. The objective was to measure the difference in return rates and conversion between the two groups, providing a clear view of the commercial impact of the tool.

the results

The results of the test were clear and commercially significant:

  • Decrease in Returns: Shoppers using the virtual try-on feature returned items 13.1% less often than those who did not. When customers can visualise how a garment fits their body type, they order with confidence — not just in case.
  • Increase in Conversion: The group with access to virtual try-on converted at a rate 3.5% higher than the control group, reflecting the boost in purchase confidence the feature provides.
