Did you know most product returns in e-commerce and online shopping are size and fit related?

When it comes to Fashion E-commerces and Online Shopping, the number one driver of returns is the fit of the actual garment and consistency of fit within a brand. Some size-related returns happen since customers do not know what size to choose, but most fit-related returns occur due to the struggle of creating consistent fit and knowing your customers' fit and bodies in the online shopping landscape.

Accepting high return rates & assuming product sizings without customer data is not a solution.

Avoid benchmarking against industry return rates. Your focus should be only on YOUR OWN RETURN RATES. How can you utilize customer data to guarantee the right fit every time and see your return rates decrease? Don't let imperfect sizing go undetected due to lack of valid data on fit of your customers!

Poor fit leads to lower brand loyalty.

Poor fit makes it harder to create bestsellers.

Returns are a huge cost driver. 20% of an items price on overage goes into returns.

Other sizing tools don’t focus on the real problem.

Returns are the real problem. Other sizing tools focus on short-term impact by giving customers the feeling of making the right decision with inaccurate size prediction. This leads to increase in conversion, but doesn’t solve the issue of sizing and the returns.

Most use rough statistical estimations based on other brands or return rates, not individual products.Poor fit leads to lower brand loyalty.

By neglecting return rates without data-driven suggestion optimization, and focusing only on conversions, leads to a conversion increase, but no return reductions. And it does not tackle the root cause: fit of the actual garment.Poor fit makes it harder to create bestsellers.

The overall accuracy of other sizing tools is extremely low.

Not optimizing your fit & sizing costs you a huge amount of money per month.
