Turn the uploaded black line technical flat into a polished fashion concept render of the same original jacket. Preserve the exact front-facing, hip-length boxy silhouette, wide straight sleeves, upright closed band collar, straight center zipper, two square patch pockets, and hem. The collar is a short rectangular stand collar, not a V neck, not a shawl collar, and not a lapel. Fill the garment with soft sage-green cotton twill, add restrained fabric folds and visible seam construction, clean warm-white studio background, garment only, no human, no mannequin, no hanger, no text, no logos, no extra pockets or accessories.
