Complete Fabric Guide

Choosing cloth for a bespoke suit

Selecting fabric is a constrained optimization problem: you are balancing drape, seasonal comfort, wrinkle recovery, and service life under abrasion, flexing, and pressing. This guide covers the world's leading mills, how to read Super Numbers, the six most important weave families, and what to choose by garment type.

Where to start

Three foundation cloths

The fastest way to build a coherent bespoke wardrobe is to anchor around three technical baselines, then branch into luxury fibers and speciality weaves from there.

01

Three-season workhorse

Midweight worsted wool around 260 g/m², Super 110s–120s. Fine enough for a refined hand, robust enough for frequent wear. This cloth should anchor your wardrobe before anything else.

02

Travel & heat cloth

High-twist yarn in an open porous weave ("Fresco" or tropical class). Positioned around breathability and wrinkle resistance as its central performance proposition. Essential for warm climates and frequent fliers.

03

Cold-weather coating

Woolen, flannel, tweed, or melton family. Weight and finishing drive warmth. Historic British overcoat selections run from roughly 500 g upward into heavy greatcoat territory. Choose based on climate and intended use.

Mill Directory

The world's leading cloth houses

Italian mills are generally known for softness, lightness, and fluid drape — ideal for modern silhouettes and warmer climates. British and French houses tend toward heavier, more structured cloth, associated with traditional English tailoring.

Dormeuil

France · Est. 1842

Exotic fibers, wool-silk-cashmere blends, statement patterns

A French luxury cloth house founded in 1842, famous for bold patterns, exotic fiber blends, and extraordinary cloths like the Amadeus. Dormeuil sources some of the world's rarest fibers for its top collections.

Ermenegildo Zegna

Italy · Est. 1910

Technical wool, travel fabrics, Super 150s+

A leader in technical innovation and fine merino wool. Zegna's Traveller and 15 Mil Mil lines are benchmarks for high-performance suiting fabrics used by bespoke tailors worldwide.

Holland & Sherry

Technical Reference

Super Numbers explained

The "Super S" designation is codified by the International Wool Textile Organisation (IWTO) and ties directly to maximum fiber diameter in microns. Higher numbers mean finer, softer fibers — but finer fibers are also more fragile. For a durable daily suit, Super 110s to 130s is the recommended range.

LabelMax fiber diameter (µm)Practical guidance
Super 80s19.75 µmRobust workhorse territory
Super 100s18.75 µmClassic everyday suiting baseline
Super 110s18.25 µmRefined hand while still durable for frequent wear
Super 120s17.75 µmSofter and cleaner; durability depends more on weave and finish
Super 130s17.25 µmLuxury daily wear if construction is sound
Super 150s16.25 µmNoticeably finer; best for careful rotation
Super 180s14.75 µmFragility risk increases; reserve for occasion or light wear
Super 200s13.75 µmUltra-fine; prioritize drape and hand over service life

Weave Guide

The six weaves that define tailoring

Weave structure has as much impact on drape, breathability, and performance as fiber quality. Understanding these six families lets you make informed choices across suits, blazers, trousers, and formalwear.

Suits, trousers, blazers

Worsted / Classic Twill

Dense, smooth, and structured. The backbone of most business suiting. Twill weaves hold a crease line well and resist abrasion better than plain weaves of the same weight. Midweight worsted around 260 g/m² is the most versatile starting point for a bespoke wardrobe.

Summer suits, travel suiting

High-Twist / Fresco

Yarns are spun with extra twist before weaving, creating a porous, open structure that maximizes airflow and wrinkle recovery. The hand feels "dry" rather than soft. Top choice for hot climates and frequent travelers who need a suit that bounces back without pressing.

Winter suits, overcoats

Flannel / Woolen

A brushed finish creates a soft, lofty surface that traps warmth. Heavier than worsted — typically 320–550+ g/m². Best for autumn and winter wear. Requires careful pressing to avoid shine and a dedicated dry cleaner who understands woolen cloths.

Tuxedos, dinner jackets

Barathea

A broken rib or broken twill-like surface that produces a fine, matte texture with almost no visible grain. The canonical cloth for black-tie suiting. It gives depth of black under low light and camera flash without the unwanted sheen of cheaper formalwear fabrics.

Summer blazers, sport coats

Hopsack / Basket Weave

An open, basket-like interlacing that creates visible texture and improves ventilation. Widely used for warm-weather blazers precisely because the structure allows air movement. Pairs well with contrasting trousers for a smart-casual look.

Trousers, year-round suits

Cavalry Twill / Gabardine

A steep, warp-heavy twill that produces a firm hand, smooth surface, and excellent crease-holding. Historically used for military uniform trousers and now a staple for hard-wearing dress slacks. The dense weave resists seat abrasion — the biggest durability problem for trouser cloth.

Garment Guide

What to choose by garment type

🧥

Three-Season Suit

Midweight worsted wool — Super 100s to 120s, ~240–280 g/m²

The most versatile starting point. High enough fineness for a refined hand, robust enough for weekly wear. Look for a balanced twill or plain weave. If you only own one suit cloth, this is it.

✈️

Summer / Travel Suit

High-twist wool (Fresco) — porous plain weave, ~200–260 g/m²

Outperforms linen for crease recovery while staying breathable. The hand feels slightly "dry" — a worthwhile trade for a suit that survives a flight and a full day without pressing. Mohair blends work well here too for extra crispness.

❄️

Winter Suit

Wool flannel or heavier worsted — 300–400 g/m²

Weight and a brushed finish add warmth and visual depth. Flannel has a warmer, more textured surface. Heavier worsted keeps a crisper line. Both are appropriate for autumn-winter business suiting.

🎩

Tuxedo / Black Tie

Barathea or wool–mohair blend

Barathea for the classic matte finish with controlled depth of black. Wool–mohair for sharper lines and slightly more luster. Silk facings on lapels and trims are standard; avoid using silk as the main suiting cloth due to its fragility when wet.

🧭

Blazer / Sport Coat

Hopsack or textured worsted / tweed

Blazers need texture differentiation from trouser cloth. Hopsack for warm weather; tweed or a medium-weight textured worsted for year-round. The open structure of hopsack earns it a place in summer wardrobes alongside linen.

👔

Dress Trousers

Cavalry twill, gabardine, or high-twist wool

Trouser cloth lives hard — seat abrasion, knee bagging, pocket stress, and frequent cleaning. Choose structure over softness. Cavalry twill and steep twills resist abrasion naturally; high-twist wool adds crease recovery. Always request shrinkage and abrasion data.

🌧️

Overcoat / Topcoat

Wool/cashmere coating — 400–550 g/m² — or weather-treated cloth

For dry cold: dense cashmere or herringbone coating, melton, or certified tweed. For rain and travel: high-density cotton systems (extra-long staple, dense plain weave) or membrane outerwear with tailored construction. Cashmere coats at luxury level often run around 460 g/m².

Sourcing

Where to buy fabric by the yard

Most mills supply through tailors and trade bunches rather than direct retail. If you are sourcing yourself, these retailers stock premium suiting cloth.

Buying Strategy

How to source cloth like a professional

The most actionable skill in fabric selection is not memorizing mill names — it is knowing how to request the right swatches and the right technical data before committing.

The Swatch Funnel

Order 5–10 swatches per garment concept: one baseline, one lighter, one heavier, and two alternates for texture or blend. Comparing physical swatches side-by-side is the fastest way to avoid expensive mistakes.

Demand the Technical Sheet

Ask for exact weight (g/m²), composition, weave, finish, shrinkage behavior, and pressing recommendation. If durability matters, request abrasion data (Martindale method). If stain resistance matters, ask for the finish type and oil repellency grade (AATCC TM118).

Build a Rotation Plan

Durability is not just a fiber property — it's a wear frequency decision. Ultra-fine Super numbers and pure cashmere suiting reward rotation and rest. If you wear the same suit five days a week, choose a construction built for it: mid-range S-numbers, firm weave, proven finish.
