Cotton Shirting Fabric: Giza, Supima & Pima Explained
In short: Cotton is the most popular shirting fibre because it is breathable, soft and versatile. Its quality is driven mostly by staple length — the longer the fibre, the finer, stronger and smoother the cloth. Extra-long-staple grades like Egyptian Giza, Supima and Pima sit at the top; everyday cotton sits below them but still makes excellent shirts.
Why cotton dominates shirting
A shirt sits against the skin for hours, so it has to breathe, absorb moisture and feel soft — all things cotton does naturally. It is also hypoallergenic, takes dye and print beautifully, and can be woven into very different fabrics: a crisp poplin, a soft twill, a textured oxford. That single fibre covers formal, business and casual shirts across every season, which no other fibre matches.
Staple length: the number that decides quality
Cotton fibre length is graded as short, long, and extra-long staple (ELS). Longer fibres spin into finer, stronger, smoother yarn with less surface fuzz — so they produce fabric that is softer, more durable, holds colour better and develops a subtle lustre. When you see premium shirting described as "long-staple" or "ELS," this is what it means.
The premium cotton grades
| Grade | Origin | Why it's prized |
|---|---|---|
| Egyptian (Giza) | Nile region, Egypt | ELS; Giza 45 & 87 are the finest, used in luxury dress shirts |
| Supima | USA (certified Pima) | Trademark-certified American ELS Pima; consistent quality and traceability |
| Pima | USA, Peru | ELS; soft, strong and lustrous at a more accessible price |
| Sea Island | Caribbean | Rare ELS, historically the most exclusive cotton |
| Upland / standard | Worldwide (incl. India) | Most common; long-to-medium staple; the workhorse of everyday shirting |
Cotton weaves for shirts
Remember that grade and weave are separate choices. The same Pima cotton can be a smooth poplin, a draping twill, or a textured oxford. Poplin is crisp and formal, twill is soft and wrinkle-resistant, and oxford is casual and durable. Our weaves guide and poplin vs twill vs oxford cover these in full.
Weight and yarn count
Cotton shirting usually runs 120–160 GSM — lighter for drape and summer breathability, heavier for structure. Finer yarns (higher counts, e.g. 2/100s) give a lighter, smoother, more luxurious hand. See the GSM guide and thread & yarn count guide for how to read these numbers.
Pros and cons of cotton shirting
- Pros: breathable, soft, absorbent, hypoallergenic, versatile, takes colour and print well, easy to care for.
- Cons: wrinkles moderately (less in twill, more in poplin), can shrink if untreated, pure cotton needs pressing for a sharp look.
- Fixes: easy-care finishes, twill weaves, or small blends with polyester/elastane for wrinkle recovery and stretch.

FAQ
Why is cotton the most popular shirting fabric?
It is breathable, soft, absorbent, hypoallergenic and easy to care for, and it can be woven into many weaves for formal or casual shirts in any season.
What is the difference between Giza, Supima and Pima cotton?
All are extra-long-staple cottons. Giza is Egyptian, Pima is mainly US/Peruvian, and Supima is certified American Pima. Longer staple means finer, stronger, smoother yarn.
What does staple length mean?
The length of the cotton fibre. Longer staples spin into finer, smoother, stronger yarn, giving softer and more durable fabric.
Does cotton shirting wrinkle?
Pure cotton wrinkles moderately; twill wrinkles less than poplin, and easy-care finishes or small blends improve recovery.
