The Smartest Fit Engine on Shopify. Bar None.
Your shopper takes 2 photos. Our AI extracts 20+ body measurements, matches them against your size chart, and generates a color-coded fit heatmap — in under 10 seconds.
Why Size Charts Don't Work
Generic size charts are useless. “S/M/L” means something different in every brand. A medium at Zara fits differently than a medium at H&M. Your customers know this — that's why 52% of fashion returns are size-related.
The only real solution is to measure the actual body against the actual garment. That's what VTS does. Not a questionnaire. Not “true to size.” Computer vision measuring real bodies against real measurements.
The Smartest Fit Engine in Fashion
Customers enter height, weight, and gender, then upload 2 photos. Our AI captures 20+ precise measurements and maps them to a personalized color-coded fit heatmap.
Optimo VTS is the ultimate Virtual Studio App for Shopify, offering accurate sizing recommendations powered by machine learning to boost your store's performance and reduce returns.

The Methodology Behind the 94% Accuracy
Computer Vision Body Detection
Our AI uses pose estimation to identify 17 body keypoints from each photo, then applies trained measurement models to extract precise circumference and length measurements.
Multi-Point Garment Matching
Each measurement is compared against not just one but multiple measurement points from your size chart. The fit heatmap shows the precise fit quality at chest, waist, hips, shoulders, and inseam.
Confidence Scoring
Every recommendation includes a confidence score. If photo quality is too low for accurate measurement, VTS prompts the shopper to retake — preserving recommendation accuracy.
Zalando-Validated Methodology
The measurement extraction approach is based on the same computer vision methodology Zalando published in their return reduction research, which achieved a 35% reduction in size-related returns.
