How to Choose Ribbed Collar & Flat-Knit Trims for Apparel

Choosing the right ribbed collar and flat-knit trims is one of the most important decisions in apparel production. The collar is the first thing customers see and feel, and it directly affects fit, comfort, and durability. In this guide, we explain what to consider when selecting ribbed collars, flat-knit collars, and trims for T-shirts, polo shirts, hoodies, and other knitwear.

Flat-Knit Collars vs. Ribbed Collars

Flat-knit collars, also known as flat collar trims, are produced on flat knitting machines and offer a dense, refined texture. They are ideal for premium T-shirts and polo shirts. Ribbed collars feature raised vertical ridges and provide superior stretch, making them perfect for sportswear and casual wear. Choosing between them depends on the garment style, target price point, and desired hand feel.
