There is a reason the same suit silhouette looks extraordinary on one man and forgettable on another. More often than not, it is the fabric.
Natural Fibres
Wool
The king. Wool is breathable, resilient, naturally crease-resistant, and ages well. The variations within wool alone could fill a book.
| Type | Weight | Best For |
|---|---|---|
| Flannel | 12–16oz | Autumn/winter trousers and suits |
| Fresco | 9–11oz | Year-round suits, hot offices |
| Tweed | 16–20oz | Country, outerwear |
| Merino | Fine | Knitwear, base layers |
Wool that has been spun tightly will hold a crease. Wool spun loosely will drape. This is not a flaw — it is a design decision.
Cotton
Cotton is honest. It does not pretend to be more than it is. The best cottons — Sea Island, Egyptian, Supima — are noticeably different in hand and lustre.
- Poplin: smooth, tight weave, ideal for dress shirts
- Oxford cloth: softer, casual, takes wash well
- Twill: diagonal weave, adds structure, used in chinos
- Denim: the heaviest cotton weave, familiar to everyone
Linen
Linen wrinkles. This is correct. A man who is bothered by linen wrinkling should not wear linen. The wrinkle is part of the material's character — a record of the day.
Synthetic Fibres
This section is shorter by design.
- Polyester is useful in technical contexts
- Nylon has legitimate applications in outerwear
- Neither belongs in a dress shirt, trouser, or suit unless the brief is specifically performance-oriented
Blends
The conversation around blends is more nuanced than it used to be. A wool-silk blend has genuine merit — the silk adds lustre and reduces weight. A wool-cashmere blend is often better value than pure cashmere of equivalent quality.
What you are trying to avoid is the blend that exists purely to reduce cost: a 55% polyester / 45% viscose situation that mimics wool at a glance and betrays itself within a season.
Fabric Weight
Weight is measured in ounces per yard or grams per metre. It matters more than most men realise.
A 340gsm Oxford shirt will survive years of hard wear. A 120gsm shirt will look see-through under office lighting and disintegrate at the elbows within eighteen months.
When a brand does not list the fabric weight, ask yourself why.
