Blank Black T-Shirt Flat Lay Mockup

top-down flat lay mockup of a completely blank plain black or charcoal t-shirt, no print, no logo, no graphics, no text, laid flat and centered on a warm light concrete or limestone surface with smooth stones, lavender bundle, small neutral candle at bottom corners only. The shirt dominates the 1080x1080 frame with sleeves near the edges, smooth blank chest area reserved for adding a design later. Use direct overhead soft lighting, subtle transparent shadow, realistic cotton texture, premium Shopify ecommerce mockup. The dark shirt must contrast clearly against the lighter background and leave the chest area clean for light-colored 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. No model, no hanger, no props above collar, no props on chest, no angled camera, no excessive wrinkles.
