What Is AI Product Matching?

AI product matchinguses machine learning and shopper behavior data to pair users with the most suitable productsbased on preferences, fit, size, silhouette, and even lifestyle context.

It goes beyond generic size charts. Instead, it uses:

• Past purchase and return behavior
  
  
• Real-time body data (via quizzes or third-party integrations)
  
  
• Styling patterns and brand-specific fit knowledge
  
  
• Community-wide insights (what worked for others like you)
  
  

The result? Fewer sizing mistakes. More shopping success.

Why Sizing Is Brokenand AI Is Fixing It

Traditional size guides assume a universal standard. But real people have:

• Different body proportions
  
  
• Brand-to-brand sizing inconsistencies
  
  
• Fit preferences (relaxed vs. fitted)
  
  
• Fluctuating measurements over time
  
  

AI takes the guesswork out by adapting suggestions to theshopper, not the garment.
