LookSize – Virtual Fitting Room for eCommerce stores


The Problem:
There’s no universal sizing standard in the fashion industry.
Every brand uses its own sizing system, so a Medium from one brand can fit completely differently from a Medium from another. This leads to incorrect purchases, higher return rates, frustrated customers, and lost revenue.
Without a standardized sizing system, both shoppers and retailers need a smarter way to find the right fit. That's exactly where a virtual fitting room makes the difference—helping customers choose the right size with confidence before they buy.

Our virtual fitting solution integrates seamlessly with your eCommerce platform, analyzes each shopper's body measurements, and matches them with the most accurate size using your brand's sizing data.
The result? Customers shop with confidence, make better purchasing decisions, and enjoy a smoother shopping experience—leading to higher customer satisfaction, stronger loyalty, and fewer returns.

How It Works
The LookSize Virtual Fitting Room is an easy-to-use size recommendation widget that asks shoppers for a few basic body measurements and instantly recommends the best-fitting size based on the brand's sizing chart.
Customers can find their ideal size in seconds—no guesswork, no complicated size charts. Their measurements are securely saved for future purchases, making repeat shopping faster and more convenient. The result is a smoother shopping experience, greater customer confidence, and significantly fewer returns.
Virtual Fitting Rooms vs. Size Charts
Traditional size charts can help shoppers choose a size, but they still require customers to take their own measurements and interpret the results.
A virtual fitting room makes the process much faster and easier by automatically recommending the best-fitting size. This reduces guesswork, improves shopping confidence, and helps minimize returns caused by incorrect sizing.
