Photorealistic Blank Black T-Shirt Mockup

Photorealistic lifestyle apparel mockup of an adult male model wearing a completely blank plain washed black or deep navy 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: work-from-home desk with light oak surface, cream notebook, tea mug, headphones, small plant, softly blurred neutral office background. 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.
