This study integrates the Analytic Hierarchy Process (AHP) with Shape Grammar to translate cultural sources into garment structure. An expert panel of 15 raters (Round-1) was refined to 5 domain experts (Round-2). The AHP hierarchy comprises three levels (goal-criterion-alternative) with four criterion dimensions (B1-B4). Consistency metrics were audit-ready: Round-1 matrices showed CI ≈ 0.03-0.12 and CR ≈ 0.07-0.18 (two alternative-layer matrices >0.10); after expert screening, Round-2 matrices achieved CI ≈ 0.02-0.08 and CR ≈ 0.03-0.09 (CR < 0.10 for all). Headline global weights included C7 Literature & Arts = 0.233 and C4 Craft Products = 0.186. Shapegrammar rules then operationalised the prioritised criteria into 2D feature-line rewrites and 3D realisation, forming a reproducible pipeline. Numerical reporting follows three-decimal precision with decimal-point alignment, and matrices/scripts are supplied for reproduction. These results demonstrate a compact, dataforward bridge from cultural genes to controllable garment morphology.
