Alternative Product Recommendations on Size Finder
When a product is out of stock in a shopper’s size, Prime AI’s Size Finder ensures the journey doesn’t end there.
Instead of hitting a dead end, our technology provides real-time alternative product recommendations – items that are in stock and guaranteed to fit, based on the shopper’s body profile and fit preferences.
Prime AI understands your full catalogue, including how each item fits, regardless of inconsistent sizing labels or brand differences, so it can instantly match customers to the next best option, without any guesswork.

Fully customisable recommendation logic:
You decide how alternatives are served. For example, you can choose to:
Show only products from the same brand
Limit suggestions to the same category (e.g. dresses to dresses)
Prioritise the same colour across different brands or collections
Add visual similarity matching using Prime AI’s Visual Search to recommend lookalikes based on product images and attributes – with fit compatibility baked in
Why it matters
Out-of-stock moments are critical decision points. Without smart alternatives, you risk losing the sale entirely. But with Prime AI, you maintain the shopper’s flow – keeping them engaged, increasing conversion, and delivering a consistent, personalised fit experience.
It’s a win for your customer and your bottom line.
