Most buyers walk into a Bangkok tailor shop ready to talk about style and cut. Far fewer arrive with a clear sense of fabric, which is a problem, because fabric does more of the work than any other single decision. The cloth is what your skin meets, what carries the shape of the suit through ten years of wear, and what decides whether you feel sharp in a Bangkok meeting or wilted by the time you reach lunch.
This guide is the conversation a good Bangkok tailor would have with you across the consultation table about fabric, written down so you can think it through before you walk in. It is the single piece of preparation that will most change the outcome of your suit.
Louis Collections has been tailoring on Sukhumvit Road since 1985 and stocks fabrics from established mills in Italy, England and Asia. The notes below reflect what we recommend most often, why, and to whom. For the wider process of commissioning your first suit, including fittings and how to choose a tailor, see our full first-time buyer guide.
Before you handle a single bolt of cloth, answer one question: where will this suit be worn most often?
Fabric selection in Bangkok is not really about taste. It is about climate matching. A beautiful Super 150s Italian wool that looks irresistible in the fabric book will feel weightless and refined in a London office and uncomfortable on a Bangkok afternoon. A heavyweight English worsted that holds its line through ten Manhattan winters will feel like wearing a blanket on Sukhumvit.
Three useful buckets to start the conversation:
Tell your tailor where you live and where you travel, and the fabric conversation becomes a short list rather than an overwhelming one.
Italian wool is what most first-time buyers picture when they think luxury suiting. The Biella region in northern Italy has built generations of expertise in producing fine, soft, lightweight worsted wool, and the major mills (Loro Piana, Ermenegildo Zegna, Vitale Barberis Canonico, Reda, Drago, Cerruti) export to bespoke tailors worldwide.
Italian wool’s defining qualities:
Italian wool is the right answer for business wear in warm climates, evening occasions, weddings in tropical settings, and travel suits that need to look refined under heat. It is less ideal for clients who want a heavily structured silhouette or who will primarily wear the suit in cold weather.
English wool comes from a different tradition. The Huddersfield region of Yorkshire has been weaving heavier, denser worsted cloth for centuries, and English mills (Holland & Sherry, Dormeuil, Scabal, Smith Woollens) supply many of the world’s most established tailoring houses.
Where Italian wool is designed to flatter, English wool is designed to last. Its qualities:
English wool is the right answer for clients who want a traditional, structured business suit; for cold or temperate home climates; for wardrobes that are expected to last decades; and for occasions where authority and presence matter more than softness.
Quality | Italian Wool | English Wool |
Weight | Lighter (220 to 280 g) | Heavier (280 to 400 g+) |
Hand feel | Soft, smooth, silky | Firmer, denser, structured |
Drape | Flowing, natural | Crisp, defined |
Best climate | Warm to mild | Temperate to cold |
Suit style | Softer construction, gentler shoulder | Structured, more defined silhouette |
Longevity | Good with care | Exceptional |
Typical mills | Loro Piana, Zegna, VBC, Reda | Holland & Sherry, Dormeuil, Scabal |
Neither is better in the abstract. Each is better for something specific. The right answer depends on where you live, what you do, and how you want the suit to feel.
Walk into any fabric room in Bangkok and you will see numbers everywhere. Super 100s, 120s, 150s, sometimes 180s and 200s. Buyers often assume higher numbers mean better suits. That is not quite right.
The Super number measures the fineness of the individual wool fibre. Higher numbers mean finer, softer threads. But finer threads are also more delicate. A Super 180s suit feels astonishing to the touch and bruises more easily under daily wear; a Super 110s or 120s suit feels less luxurious to fingers but holds up beautifully for years.
The practical guidance:
If a tailor steers you towards a very high Super count for an everyday business suit without asking how you will wear it, ask why. Often a lower Super count from a respected mill will serve you better.
Many buyers arrive in Bangkok assuming linen is the right answer for tropical climate, and linen has its place, but the more reliable everyday choice is tropical weight wool.
Tropical wool is a high-twist, open-weave wool, typically between 200 and 260 grams, designed specifically for warm climates. Its qualities:
For a client who lives or works in Bangkok and needs a suit they can wear daily in heat without it looking exhausted by lunchtime, tropical weight wool is usually the right answer. It is also an excellent choice for wedding suits in tropical settings.
Linen is the most breathable fabric in the suiting world and one of the most characterful. In tropical heat it feels light, airy and genuinely cool. It is the right answer for a holiday wedding, a Sukhumvit summer event, or a relaxed, character-driven look.
The honest trade-off is wrinkles. Linen creases readily and visibly, and no tailor in the world has solved this. The crease is part of linen’s identity. If you can embrace that, a linen suit is a wonderful thing. If you want crisp lines all day, linen will frustrate you.
A linen-wool blend is often a useful compromise. It keeps much of the breathability and adds enough wool to soften the crease behaviour.
Cotton sits between wool and linen. More structured than linen, less formal than wool, and a comfortable everyday choice for smart-casual suits, summer blazers and trouser separates. Cotton is rarely the right answer for a primary business suit, but for a second or third suit in a tropical wardrobe, especially in lighter colours, it has real merit.
Cashmere is the softest natural fibre commonly used in suiting, and a pure cashmere suit is one of the most luxurious garments a buyer can commission. It is also the most delicate, and rarely the right answer for daily wear. Where cashmere shines is in blends. A wool-cashmere blend adds softness and slight warmth to a worsted wool, which suits cooler weather and special occasions.
Fabric weight is one of the more useful numbers in a tailoring conversation because it gives you a real sense of how the cloth will feel and behave.
Weight (grams) | Description | Best For |
180 to 220 | Very lightweight, tropical | Hot, humid climates; summer travel |
220 to 280 | Lightweight, year-round in warm climates | Bangkok daily wear; mild climates |
280 to 340 | Mid-weight, year-round in temperate climates | Versatile, most common business suits |
340 to 400 | Heavier, structured | Cooler climates; traditional business suits |
400+ | Heavyweight, winter cloth | Cold weather, overcoats, formal winter wear |
A serious tailor will tell you the weight of a fabric without being asked. If you ask and get a vague answer, that is a quiet warning sign.
Two fabrics can come from the same mill, have the same Super number, and behave very differently because of how they are woven.
Ask your tailor what weave you are looking at. The answer reveals as much about how the suit will perform as the wool type or Super number does.
If this is your first custom suit and you want a single sensible recommendation, here is the conversation we have most often at Louis Collections:
None of these are rules. They are starting points, and a good tailor will adjust them based on your build, your existing wardrobe, and how you actually live.
Louis Collections stocks an extensive range of fabrics from established mills in Italy, England and Asia, including Italian worsted wool, English worsted, tropical weight wool, linen, cotton and cashmere blends. We choose mills for consistency, durability and appropriateness to climate, not for marketing weight.
More than the fabric library itself, we put time into the conversation around it. A good fabric decision is the result of understanding where you live, what you do, what you already own and what you want this suit to do for you. Forty years of tailoring on Sukhumvit have taught us that the cloth chosen well is the foundation of a suit you will still be wearing in fifteen years.

Decide where the suit will mostly be worn, what climate it needs to perform in, and how often you will wear it. Those three answers will tell a good tailor whether you need Italian wool, English wool, tropical weight wool or linen, and roughly what weight and Super count will serve you best.
Tropical weight wool, around 200 to 260 grams, is usually the most reliable everyday choice. It breathes well, resists wrinkles better than linen, and looks appropriate in business settings. Lightweight Italian wool around Super 120s is also excellent.
Neither is better in the abstract. Italian wool is softer, lighter and drapes more naturally, which suits warm climates and softer suit construction. English wool is denser, more structured and longer-lasting, which suits cooler climates and traditional business suits. The right answer depends on where you live and how you want the suit to feel.
Super 120s refers to the fineness of the wool fibre used to weave the cloth. Higher numbers mean finer threads and a softer feel, but finer threads are also more delicate. Super 120s and 130s tend to be the sweet spot for most buyers, offering refinement without sacrificing durability.
Linen breathes beautifully and looks wonderful in tropical settings, but it creases readily and visibly. If you embrace the creases as part of the look, linen is a fine choice. If you want crisp lines through the day, a tropical weight wool or a wool-linen blend may serve you better.
Yes. Established Bangkok tailors maintain direct relationships with major Italian and English mills. Louis Collections has been sourcing from these mills for decades. Always ask which mill a fabric comes from; a serious tailor will name it.
A mid-weight Italian wool around Super 120s, in a plain weave, is the most adaptable choice. It tolerates Bangkok heat better than English cloth and holds shape better than the lightest tropical wools. Many of our long-term travelling clients build their wardrobe around this fabric weight.
A suit cut from well-chosen, mid-weight wool with full-canvas construction can last fifteen to twenty years with proper care. Lighter and finer fabrics, particularly above Super 150s, wear more delicately and are better suited to occasional rather than daily use.
