Executed a complete technical design pipeline from fabric sourcing through production liaison. Conducted a structural audit of pima cotton weight options (280–350 GSM range) and settled on a 300 GSM heavyweight that provided the luxury hand-feel while maintaining breathability. For the raglans, mapped a custom raglan geometry that maximized the natural drape of pima cotton without sacrificing shoulder articulation. Engineered offset seam placement to eliminate the visual "bulk" that often accompanies structured raglans, using a split-needle overlock technique to maintain seam elasticity across the jersey-knit fabric.

For the joggers, developed a precision cuff construction using a stay-tape system that anchors the elastic at four critical points, preventing the common jogger issue of cuff roll or sagging at the ankle. Created a complete tech pack with grading for XS–XXL, including detailed construction callouts for each seam type (flatlock shoulders, coverstitch hem, stay-tape cuff). Served as direct liaison through first and second samples, coordinating fabric approvals and production adjustments with zero revision cycles on the final prototype.
