White Technical Tennis Dress Mockup

Generate a hyper-realistic image of a white sleeveless tennis dress with a flared skirt, showcased against a dark grey gradient background that transitions from light to dark. The dress should feature a round neckline, be made of a smooth, possibly technical fabric, and have a fitted silhouette that accentuates the waist before flaring out into a short skirt. The image should capture the dress as if its floating, with a subtle shadow cast to the right, indicating a light source from the left. The overall styling should evoke a sense of modern athletic wear with a touch of elegance, suitable for a high-end fashion editorial or campaign. The dress should be centered, with the background fading into darkness towards the edges, and the shadow should be soft and natural-looking. The image should be rendered with high detail, capturing the texture of the fabric and the subtle sheen that suggests a technical or synthetic material. The lighting should be soft and diffused, with no harsh shadows or reflections, emphasizing the clean lines and minimalist design of the dress.
