Photorealistic Grey Crew Neck T-Shirt Flat Lay

1080x1080 pixels, square format 1:1 aspect ratio. Professional photorealistic product photography, top-down flat lay perspective. A blank heather grey crew neck t-shirt with no design, no logos, no graphics, no text, no prints, laying on a soft, cream-colored linen fabric surface. The t-shirt is made of realistic soft cotton fabric with visible natural cotton weave and textile texture. The material looks like authentic worn-in cotton, not smooth, not shiny, not synthetic, not digitally rendered. The t-shirt fills the entire frame. The sleeve cuffs touch the left and right edges of the image—no background visible between the sleeves and the image borders. The collar nearly touches the top edge. The bottom hem reaches the bottom edge. Only tiny triangular corners of background are visible for props. The bottom hem is casually knotted on one side, creating a stylish gathered twist in the fabric. Folded beige cashmere cardigan in the bottom left corner (60% cropped), a pair of reading glasses in the top right corner (50% cropped), a small lavender sprig in the bottom right corner. Soft diffused lighting from above with subtle shadows. 8K quality, photorealistic
