Not all cotton is created equal. The softness of your favourite shirt, the crispness of your bed linen and even the way fabric ages over time all come down to cotton quality. Understanding how quality is measured helps you choose pieces that feel better, last longer and perform exactly as you expect. Premium cotton is distinguished through careful evaluation of fibre characteristics, processing methods and final fabric construction. In this article we breakdown exactly what you should consider when purchasing cotton.
1. Cotton Grades
The cotton grading system evaluates several key factors that determine fibre quality and ultimate fabric performance. While staple length remains the primary indicator, micronaire measures fibre fineness and maturity. This affects processing characteristics and the final material. Strength testing ensures fibres can withstand manufacturing processes and extended use, while colour grade evaluates the natural brightness and consistency of the raw cotton.
Below in our cotton chart, you’ll see the grades ranked as “middling”. This is the term used to classify the cotton's quality regarding the factors above. Good middling is considered the highest grade, followed by strict middling, middling, strict low middling and low middling.
2. Fibre Construction
GSM (grams per square meter) indicates fabric weight and density, directly influencing drape, durability and thermal properties. Gauge refers to the fineness of construction, particularly relevant in knitted fabrics where closer gauge creates smoother, more refined surfaces. These technical specifications work together with fibre quality to determine the final fabric's characteristics and appropriate applications.
3. Certification Standards
Our commitment to quality extends beyond basic fibre characteristics to encompass comprehensive certifications that ensure both excellence and responsibility. Organic cotton certification guarantees cultivation without synthetic pesticides or fertilisers, while GOTS (Global Organic Textile Standard) certification ensures organic integrity throughout the entire supply chain, from fibre to finished fabric.
OEKO-TEX certification provides additional assurance by testing for harmful substances and ensuring human-ecological safety. These certifications offer customers tangible evidence of quality while supporting environmental responsibility.
We actively source these certifications, not as badges, but rather as part of a broader commitment to respect both people and the planet.
"Every decision we make – from farm to final stitch – carries a level of responsibility. Certifications help us prove our commitment to doing the right thing but it’s actually the intention behind them that matters the most." (Lauren Knowlson, Head of Product).
