Jersey, rib and interlock: look closer
Fabric structure is another reason to look beyond colour.

Two similar-looking knit samples can feel quite different. Jersey, rib and interlock refer to different knitted structures. Rib’s vertical ridges and interlock’s double-knit construction are useful starting points for comparison, but they do not replace examining an actual sample.
Follow the name with a practical comparison
A fabric name alone does not guarantee a particular garment result. Composition, weight and finishing also matter. Look at both sides and the edge of the sample, then consider it in the intended collar or body panel. Where different materials meet in one garment, assess them together.
Rather than writing only “rib” in a brief, include the approved sample. Small details like this help the buyer and manufacturer understand the same material.
