Ghost Mannequin White T-Shirt Mockup

Premium ghost mannequin 3D mockup of a completely blank plain white t-shirt, front-facing, no print, no text, no logo, invisible body form only implied by realistic drape. Shirt centered and large in a 1080x1080 square frame, chest area smooth and clear for later design placement. Background dark charcoal for contrast, soft overhead studio lighting, subtle shadow, realistic cotton fabric and seams, ecommerce-ready. No existing design, no typography, no brand logo, no visible mannequin, no human model, no face, no arms, no hanger, no busy background, no harsh shadows.
