Shopify App : Faslet Size Me Up

We ensure that every customer buys the right size in one go.


Here at Faslet, we created a personal size recommendation widget, tailored to your online fashion single or multibrand store. Our innovative algorithm helps your customers find the right size in just a few easy steps.

Save the planet while increasing your profit

Confident they have got the perfect fit in their shopping basket, customers are much more likely to proceed to checkout. Not only does this ensure increased conversion rates for your online retail store, we also significantly reduce the impact on clothing returns. Less returns helps you save costs and reduce CO2 emissions.
