Ultra-Realistic Athleisure Editorial: Oversized Sweatshirt & Technical Pants

Use the uploaded product image as the primary reference if available; otherwise create an oversized premium active sweatshirt paired with fitted technical ankle pants for fictional unisex brand Forme District. Preserve any referenced product with absolute visual fidelity including print or logo placement, colors, fabric, ribbing, stitching, neckline, cuffs, hem, pockets, pants construction, and proportions. Show a fashion model seated sideways on a broad minimalist concrete staircase, one foot positioned on a lower step and the other leg bent on the same level, torso slightly forward with elbows relaxed and garment front clearly visible. Use raw brutalist architecture with smooth concrete planes as the background and no decorative props. Illuminate with a hard shaft of midday sunlight entering from above, creating graphic light-and-shadow blocks while keeping the product correctly exposed. Editorial full-body composition from a diagonal camera angle, premium street-athleisure aesthetic, realistic fabric volume, correct anatomy, clean hands, sharp details, no watermark, no unwanted text. Ultra-realistic 8K fashion campaign, aspect ratio 3:4.
