Create a realistic 3D mockup of an oversized unisex T-shirt floating in the center of the frame. The T-shirt should have a soft, displayed in a front-facing view, showcasing the entire design clearly. T-shirt Style: Drop-shoulder, oversized fit with relaxed sleeves and loose silhouette. Color & Texture: Use smooth shadows and fabric folds to maintain realism. Reflect natural cloth movement. Background: Use a clean gradient or smooth background that matches or complements the color palette of the t-shirt (auto-adjust background color based on the t-shirt dominant color). Lighting: Soft diffused lighting from the top or front to highlight fabric texture and volume, with a subtle floating shadow below the T-shirt. Aspect Ratio: 4:5
