How Fit Tech Can Power Better Merchandising Decisions

Retailers often think of fit tech as a shopper-facing solution.
But the smartest ones are already using it behind the scenes—as a data engine for merchandising. When you know which sizes get bought, which ones get returned, and what customers actually keep, you’re not just improving CX. You’re building a feedback loop for smarter buying, planning, and design.
At Secret Sauce, we’ve seen partners use Fit Predictor data for more than just fit. It’s become a strategic asset for:
- Return Reduction by Style or SKU
Which jeans are driving the most returns due to fit? Which styles run small in practice? Retailers use this intel to refine their product mix and improve size guidance. - Size Curve Optimization
By understanding not just what sizes are sold, but what’s returned—and why—buyers can make smarter calls on size distribution per SKU. - Assortment Planning
Fit-related insights reveal category blind spots. Are wide-leg pants underperforming because the size guidance is off? Are returns clustered in a particular product type? - Informing Future Design
Designers and product developers can use return behavior to fine-tune future collections—from adjusting rise or sleeve length to deciding which fabrics to avoid. - Aligning Fit Experience with Brand Promise
Is the sizing experience as premium or seamless as the brand positioning suggests? Fit data gives qualitative clues that drive better alignment between experience and expectation.
When fit intelligence feeds your merchandising process, you’re no longer reacting to returns—you’re designing around them.
