T-Shirt

Fabric: 100 % cotton or high‑quality blend; look for long‑staple cotton for softness & durability.

Weight / weave: A tighter, denser knit means better durability; fabrics that are too thin may stretch, fade or sag.

Construction: Good stitching (double‑needle hems, reinforced seams), collar that holds shape, proper fit (shoulder seams aligned).

Fit & comfort: Size M should match your chest/shoulder measurement, the tee should skim well (not too baggy or tight), the sleeves & length proportionate.

Colour & style: Since you want blue, ensure the dye quality is good, colour fastness (doesn’t bleed/fade), and the shade of blue matches your style (navy, royal, sky blue, etc).
