The hidden cost of inconsistent sizing
Grading that drifts even slightly between sizes doesn't stay small — it compounds into real production risk.
Distorted proportions or silhouette across your size run lead to fit complaints at the worst possible stage.
Bad grading means cut fabric that doesn't sew up right — and production delays while it's corrected.
Sizing complaints after launch are far more expensive to fix than getting the grade rules right up front.
Sizing inconsistency is one of the fastest ways to lose customer trust in a competitive market.
We eliminate the guesswork — your patterns scale perfectly across all sizes without distorting proportions.
Built for brands who can't afford to guess
