Catches launched its generative AI with sizing technology (“RealFit”), a new AI-powered online consumer experience built on Nvidia’s CUDA platform, to provide real sizing, fit and drape for fashion e-commerce.
RealFit is a capability that allows shoppers to see, with mirror-like realism, exactly how a garment will fit, drape and move on their own body before purchasing. Shoppers enter their measurements and a photograph to generate a digital twin, then experience any garment in the collection on their own body, toggling between sizes to know exactly how each piece will fit. The first public use of Catches’ RealFit went live on the Amiri website. Catches is currently working with a number of other brands, scheduled to launch in the next few months.
“Accelerated computing is unlocking new possibilities for digital fashion experiences,” said Azita Martin, Nvidia’s vice president and general manager of AI for retail and consumer packaged goods. “Catches has introduced an AI-based virtual try-on with physics-based simulation for fabric movements and sizing, built on Nvidia Omniverse and [an] accelerated computing platform. Amiri is pioneering this innovation, and we’re collaborating with Catches as an independent software vendor to bring these capabilities to more fashion brands.”
“Amiri is about community, craft and innovation,” said Mike Amiri, founder and creative director of Amiri. “For me, Catches RealFit embodies all of these values, bringing them into a modern digital context. The idea of digital craft—tailoring each client’s experience to feel personal and unique—and the ability to connect with them, whether in store or through our digital flagship, strengthens the Amiri universe. This partnership represents the next step in how we engage with our clients around the world.”
“Catches is solving one of the biggest problems in fashion e-commerce—customers not knowing whether a garment will fit them. Fit uncertainty lowers online conversions and causes over 50% return rates in some categories,” said Ed Voyce, founder and CEO of Catches. “Catches RealFit technology fixes this by providing customers a personalized photorealistic experience that understands real materials, cuts, and true sizing and fit. With the support of Nvidia, we are providing brands a fully customized offering and a customer experience for the AI era.”
Catches has raised $10 million from the world’s leading luxury voices, including Antoine Arnault and Natalia Vodianova Arnault; Roy Chung, founder of Apollo.io; Dillon Erb, founder of Paperspace; Gary Sheinbaum, former CEO for Tommy Hilfiger; and Sarah Willersdorf, former head of luxury for BCG.
“In fashion, the relationship between a garment and the person wearing it is essential. Any technology that helps bring that understanding into the online environment is an important step forward,” said Antoine Arnault, director of image and environment at LVMH.
“AI has largely lived in the digital world, trying to imitate reality without truly understanding it,” said Natalia Vodianova, supermodel, philanthropist and impact investor. “Catches changes that by anchoring AI to the laws of physics, so it doesn’t guess how a garment drapes or fits; it knows. That bridge between the physical and digital world is a profound shift, and fashion is only the beginning.”
Catches spent two years building a proprietary GPU-accelerated simulation framework, modeled and integrated on physical fabrics before applying AI to scale it. The result is an exact 1:1 representation of the real fabric’s weight, structure, drape and movement. For shoppers, RealFit delivers the confidence of a fitting room from anywhere in the world. For brands, it opens a meaningful opportunity to deepen the connection between customer and product, increase purchase conversions and significantly reduce fit-related returns, the leading driver of reverse logistics costs across fashion e-commerce.
