Each brand's fit tendency, runs small, true to size, or runs large, is set by comparing the brand's published size chart to a universal 0–20 numeric scale, then weighted with consistent shopper signals (return reasons, sizing reviews, and community reports across categories).
What the badges mean
- Runs small, most shoppers size up at least one increment for their usual fit.
- True to size, your usual size is the safest first choice across most categories.
- Runs large, most shoppers size down for their usual fit.
When the recommendation is most reliable
- You've added your usual top and bottom size to your profile.
- The brand has a published size chart we've verified.
- You're searching a core category (tops, bottoms, dresses, denim) rather than an outlier like swim or outerwear.
- The badge is shown without a "limited data" caveat on the brand page.
What can change the answer
- Fabric: stretch denim runs more relaxed than rigid denim, even within the same brand.
- Cut: structured tailoring fits closer than relaxed or oversized silhouettes.
- Region: EU, UK, and US labels differ, we normalize to your usual size system.
