White Zip-Up Jacket Product Mockup

Generate a hyper-realistic product mockup image of a white, zip-up jacket with a high collar and long sleeves, showcased against a clean, minimalist background. The jacket should be centered in the frame, with its front side facing forward and the zipper partially unzipped, revealing a subtle contrast in texture or color underneath. The image should capture detailed textures of the jacket's material, likely a smooth, possibly waterproof or windbreaker fabric, and the metallic sheen of the zipper. The lighting should be soft and natural, casting a gentle shadow underneath the jacket to enhance its three-dimensionality. The background should be a light gray or white, free of distractions, and the overall composition should convey a sense of modernity and simplicity. The image should be devoid of any watermarks or logos and should resemble a high-end design editorial or campaign photograph. The jacket's cuffs and hem should be slightly ribbed, adding a touch of sporty elegance. The overall visual should be crisp, with accurate mockup construction and refined styling that highlights the garment's features.
