In short
The best suit fabric is wool, specifically a 280–340g worsted wool, because it breathes, recovers from creasing and drapes cleanly. Cotton and linen are cooler but crease more; cashmere and silk blends add luxury but are less hard-wearing for daily use.
Cloth does more than colour the suit. It controls how the jacket hangs, how warm you are, how quickly the garment creases and how long it lasts. Most Roomten suits are cut from wool, but the right wool depends on when and where you will wear it.
Wool: the default choice
Wool is breathable, naturally elastic and water-resistant. A good worsted wool recovers from a day at a desk and still looks presentable for dinner. For a first suit, choose a 280–320g plain worsted in navy or charcoal.
Linen, cotton and summer cloths
- Linen is the coolest summer cloth but creases immediately; wear it deliberately.
- Cotton is casual, matte and comfortable; better for unstructured jackets than business suits.
- Wool-linen or wool-silk blends give the coolness of linen with better recovery.
Luxury fibres
Cashmere adds softness and warmth but is best reserved for jackets and overcoats rather than everyday trousers. Silk gives a subtle sheen for evening cloths. Mohair is crisp, light and holds its shape beautifully in warm weather.
How to decide
Start with the occasion, then the season, then the weight. A business wardrobe needs hard-wearing worsteds; a summer wedding calls for something lighter and more relaxed. During a Roomten appointment we drape the cloths against your shoulder so you can feel the difference.
