# GenAI Sizing Technologies CATCHES's RealFit Enhances E-Commerce Fashion with Movement and Drape By Laura McQuarrie | Published 2026-03-18 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/realfit References: [businesswire](https://www.businesswire.com/news/home/20260316837622/en/CATCHES-Launches-Generative-AI-with-Physics-Based-Sizing-Technology-for-Fashion-E-Commerce-with-AMIRI-Powered-by-NVIDIA) & [catches.ai](http://www.catches.ai)  The true way a garment drapes, stretches and moves with the body can be difficult to convey on a flat product page, where the life and dimension of fabric is often lost in static images, prompting physics-backed AI company CATCHES to create its [Generative AI with Sizing technology](https://www.trendhunter.com/trends/laws-of-motion), RealFit. Built on [NVIDIA’s](https://www.trendhunter.com/trends/ai-retail-shopping-assistant) CUDA platform, this online consumer experience powered by artificial intelligence conveys real sizing, fit and drape, promising "mirror-like realism" so that consumers can shop confidently and really get a sense of how a garment will look on their own body before purchasing. Shoppers enter their measurements and a photograph to generate their [digital twin](https://www.trendhunter.com/trends/wear-ai), then they can toggle between different sizes to see the differences, and determine which might be best for the look and feel they're after. ## Trend Insights (Trend Hunter) - Score: 6.2/10 - Popularity: 56% | Activity: 63% | Freshness: 66% - Audience gender: 10% men, 90% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [AI](https://www.trendhunter.com/ai) ## Key Themes ### Why This Trend Is Growing - **Generative Fit Visualization:** This enables realistic previews of how garments conform to individual bodies, reducing uncertainty in online purchases and altering expectations for product presentation. - **Physics-backed Digital Twins:** Digital replicas that model fabric drape and stretch bring material science into consumer-facing interfaces, shifting value toward simulation accuracy over static photography. - **Size-adaptive E-commerce:** Interactive size toggles that show proportional differences create a new standard for personalization, changing return dynamics and customer sizing confidence. ### Industries Being Reshaped - **Online Fashion Retail:** Retail platforms incorporating realistic fit visualization can transform conversion rates and reshape merchandising strategies around simulated try-on experiences. - **Virtual Try-on Platforms:** Providers of AR/VR fitting rooms gain differentiation by integrating physics-based drape models, positioning the industry toward scientifically validated realism. - **Apparel Manufacturing and Supply Chain:** Manufacturers able to leverage precise virtual fitting data may optimize grading, reduce overproduction, and align inventory with observed consumer fit preferences. ## Related on Trend Hunter - [Smart Fashion Management Apps](https://www.trendhunter.com/trends/acloset.md) - [AI Creative Studios](https://www.trendhunter.com/trends/snapstudio.md) - [GenAI Fashion Lenses](https://www.trendhunter.com/trends/sponsored-ai-lens-on-snapchat.md) - [AI-Powered Shoppable Runways](https://www.trendhunter.com/trends/front-row-ai.md) - [Fashion Design AI](https://www.trendhunter.com/trends/dripsmith.md) - [AI Face Analyzers](https://www.trendhunter.com/trends/face-shape-detector.md) - [AI Outfit Planners](https://www.trendhunter.com/trends/moodrobe-ai.md) - [Cotton Tee Fragrances](https://www.trendhunter.com/trends/his-white-tshirt.md) - [Virtual Styling Tools](https://www.trendhunter.com/trends/outfits-ai.md)
