Compare the whole silhouette

Start with a T-shirt you like and record its flat chest width, shoulder width, body length and sleeve length. Check how the seller takes each measurement before comparing. A short, wide body can look very different from a narrow, long body at the same chest width. Nike's official tops chart is based on body measurements; it should not be compared directly with an unexplained flat garment number. Check the selected product's own sizing information.

Read fabric and graphic information separately

Request the fibre composition and close-up photographs of the neck, seams and printed area. A large graphic does not tell you whether it is printed, embroidered or applied as a transfer. Ask which process the seller describes if texture or care matters to you. For jerseys, check the exact version and whether the photographed badges are included. Avoid treating words such as 'premium', 'breathable' or 'heavyweight' as measured performance data without supporting details.

Use the care label, including print restrictions

UNIQLO's cotton-care guidance begins with checking the product label and separating colours for washing. Use that as a starting point, then follow the actual T-shirt's instructions for washing, drying and ironing. A cotton body does not automatically make a printed area suitable for direct heat. Before washing a new purchase, photograph the composition and care label and check for different instructions for the decoration. Do not promise a shrinkage percentage when the seller has not supplied one.
