Removing Image on Shirt while Maintaining Shading and Lighting Gradient

[Ofnuts]

Afterthought: instead of Paint with black/Multiply with synthetic creases an alternative technique could be:

• Create synthetic creases with solid noise, and stretch the range
  
• Run Filter>Distorts>Ripple to add a more natural look
  
• Sample lighter/darker tones on original layer as FG/BG colors,
  
• Apply gradient map with an FG-to-BG gradient
