Question: I'm tired of returning clothes that don't fit. Can you recommend a tool that helps with size recommendations?

One of the most interesting is WAIR, an AI for e-commerce sites. It's trained on a huge database of 3D body scans to make personalized and accurate size recommendations. WAIR's technology can lower return rates and increase conversions, making it a good option for retailers that want to improve customer satisfaction and revenue.

Another contender is Usizy, a full-stack machine learning platform for retailers. It includes a Size Adviser tool that suggests the specific size for each customer, as well as other features like stock optimization and dynamic pricing. Usizy has been tested on more than 500 eCommerce sites, resulting in a notable increase in conversions and customer loyalty.

For a more customized experience, Fit Analytics offers personalized size advice based on body measurements, purchase history and return data. Its Fit Finder feature ensures the right size is ordered the first time, which can help retailers cut down on returns. It's used by companies like ASOS and Zara, so it's a good option if you want to improve your e-commerce site.
