retro sports jacket 3d model

Create a realistic 3D model of a retro 1990s Russian/post-Soviet men's sports zip-up jacket. Oversized, relaxed fit with broad shoulders, loose sleeves and a slightly bulky silhouette. The main body is deep desaturated forest green (#174A42), made from matte-to-slightly-satin synthetic tracksuit fabric with subtle realistic texture and natural folds. Full-length front zipper. The jacket is partially unzipped at the upper chest, with the neckline clearly open. The collar is wide, dark burgundy/wine red (#6E123D), turned outward and folded down on both sides of the neck, clearly visible around the open neckline. The collar should have natural thickness and soft folds. Long loose green sleeves with natural wrinkles around elbows and wrists, slightly gathered cuffs. Straight slightly loose lower hem. Simple authentic 1990s sportswear construction, clean topology, realistic fabric thickness, seams and stitching. Isolated garment, front-facing, neutral A-pose, entire jacket visible.
