Photorealistic Blank Black T-Shirt Mockup

Photorealistic lifestyle apparel mockup of an adult female model wearing a completely blank plain deep charcoal or washed black t-shirt, no print, no logo, no text, no graphics. Front-facing pose with the shirt chest fully visible, smooth, and unobstructed for adding a design later. Background: cozy reading nook with oatmeal armchair, pale wood bookshelf, tea mug, headphones, soft warm lamp glow, textured cream throw. Mood: calm, self-aware, cozy, overstimulated-but-functioning, not influencer-perfect. Natural soft lighting, premium Shopify ad creative, square 1080x1080. The dark shirt must contrast clearly with the lighter/warm background and keep the chest readable for light ink artwork overlay. No shirt design, no words, no logo, no watermark, no black-on-black background, no low-contrast dark wall directly behind the shirt, no hair/hands/props covering chest, no jacket/cardigan/overshirt covering shirt, no medical or therapy claims, no harsh dramatic shadows, no clutter overpowering the shirt, no fake brand tags. For dark shirts, avoid muddy lighting and keep edges clearly separated from the background.
