Bio-Cotton T-Shirt Mockup
"A realistic mockup of a black T-shirt made from 100% bio-washed cotton, displayed on a wooden hanger. The mockup should show both the front and back views of the T-shirt, with clear details of the fabric texture and stitching. The wooden hanger should have a smooth, polished finish, and the T-shirt should hang naturally on it. Use a simple, neutral background to emphasize the T-shirt design."
