The main types of wool suits are worsted wool (smooth and year-round), flannel (soft and warm), tweed (rugged and textured), tropical or high-twist wool (light and breathable), and blends like wool-linen, wool-mohair and stretch wool. Merino is the type of sheep most fine suiting wool comes from, and "Super" numbers tell you how fine the fibre is. This guide explains each one simply, so you can pick the right suit for Indian weather and your occasions. You can browse ready-to-wear options in the VJV Now men's suit collection.

First, Worsted vs Woollen: The Basic Difference
Every wool fabric starts as yarn, and there are two main ways to spin it:
- Worsted yarn: long wool fibres are combed so they lie parallel, then tightly twisted. The result is a smooth, strong, fine fabric. Most business and wedding suits are worsted.
- Woollen yarn: shorter fibres are carded but not combed, so they stay a little messy and airy. The result is softer, fuzzier and warmer. Tweed and many traditional flannels are woollen.
Fun fact: "worsted" comes from Worstead, a village in Norfolk, England, which became a weaving centre in the Middle Ages.
1. Worsted Wool Suits
If you buy one wool suit, make it worsted. It is smooth, drapes cleanly, resists wrinkles better than most fabrics and keeps a sharp trouser crease. A mid-weight worsted (around 250-300 grams per metre) is often called a "four-season" or "all-season" cloth.
- Pros: durable, crisp, formal, easy to care for.
- Cons: can feel warm outdoors in an Indian summer if the fabric is heavy.
- Choose it for: office wear, interviews, weddings and receptions.
2. Tropical and High-Twist Wool Suits
Many people think wool is only for winter. Not true. Tropical wool is a lightweight worsted (roughly 200-250 grams per metre) with an open weave that lets air through. High-twist wool (sometimes sold as "fresco") uses tightly twisted yarns that feel dry and springy, breathe well and bounce back from creases.
For hot Indian cities, a light, high-twist wool is one of the most comfortable suiting fabrics you can wear, especially if you travel or attend day events.
3. Flannel Wool Suits
Flannel is wool that has been brushed (napped) to raise the fibres, which gives it a soft, slightly fuzzy surface and a matte look. That raised surface traps air, so flannel is one of the warmest suit fabrics.
- Look: soft, matte and rich, especially in grey, charcoal and brown.
- Weight: usually heavier than worsted suiting.
- Choose it for: winter in Delhi, Punjab, Rajasthan and the hills, or cold evening events.
4. Tweed Wool Suits
Tweed is a rough, textured woollen cloth, traditionally woven in Scotland and Ireland. It usually comes in patterns like herringbone, checks and flecked earthy colours. The most famous is Harris Tweed, which by law must be handwoven by islanders in the Outer Hebrides of Scotland.
Tweed is thick and warm (often 350 grams per metre or more), so in India it is best for peak winter, hill stations and outdoor winter weddings. A tweed jacket or waistcoat worn as a separate is an easy way to try it. Want groom ideas? Read our tweed suit style for grooms.

5. Merino Wool: A Fibre, Not a Weave
You will often see "merino" on suit labels. Merino is a breed of sheep with very fine, soft fleece. The breed was developed in Spain, and today most merino wool comes from Australia. Most good suiting wool, whether worsted, flannel or tropical, is spun from merino fibres.
So a "merino wool suit" is not a separate type of weave. It simply tells you the fibre is fine and soft.
6. What Do Super 100s, 120s and 150s Mean?
"Super" numbers describe how fine the wool fibre is. The higher the number, the thinner the fibre. As a rough guide, Super 100s is about 18.5 microns and each step of 10 is about half a micron finer.
- Super 100s-120s: the sweet spot for most suits. Soft, but tough enough for regular wear.
- Super 130s-150s: very soft with a smooth sheen, but wrinkles and wears out faster.
- Super 160s and above: luxury fabric for occasional wear, not daily office use.
Higher is not always better. For a suit you will wear often, Super 110s-130s is usually the best balance.
7. "Italian Wool" Suits
"Italian wool" usually means the cloth was spun and woven by an Italian mill, not that the sheep were Italian. Many famous suiting mills are in the Biella area of northern Italy, and much of the raw wool they use comes from Australian merino sheep. Italian cloths are known for a soft handle and rich colours.
8. Wool Blends: Linen, Mohair, Stretch and Polyester
- Wool-linen: adds breathability and a relaxed, textured look. Great for summer and day weddings, but it creases more.
- Wool-mohair: mohair comes from the Angora goat. It adds a slight sheen and a crisp, cool feel, which is why it is popular for evening suits.
- Stretch wool: wool with a small amount of elastane for easy movement. Good for travel and long days.
- Wool-polyester (often called terry-wool in India): more affordable, wrinkle-resistant and easy to maintain, but less breathable than pure wool.
Wool or Poly-Viscose? What Works in Indian Weather
Pure wool is wonderful, but it is not the only good choice in India. Poly-viscose blends are lightweight, hold their shape and resist wrinkles, which makes them practical for humid cities, long wedding days and frequent travel. They are also easier on the budget and simple to care for.
The VJV Now designer suits are made in a lightweight polyester-viscose blend, tailored with a structured shoulder, and you can choose your blazer size and trouser waist separately (with an optional matching waistcoat). For peak North Indian winter, layer your suit with a long coat.

How to Care for a Wool Suit
- Brush the suit after wearing to remove dust, and hang it on a wide, shaped hanger.
- Give it a day of rest between wears so the fibres recover.
- Steam out wrinkles instead of ironing hard; use a pressing cloth if you must iron.
- Dry clean only a few times a year, or when it is really dirty.
- Store it in a breathable cotton bag with cedar or neem to keep moths away, especially during the monsoon.

Frequently Asked Questions
What is the best type of wool for a suit?
For most people, a mid-weight worsted wool in Super 110s-130s is the best all-round choice. It is smooth, durable and works for office and weddings.
Can I wear a wool suit in summer in India?
Yes, if you choose a lightweight tropical or high-twist wool. These fabrics breathe well. Avoid flannel and tweed in summer.
What is the difference between worsted and flannel?
Worsted is smooth and crisp. Flannel is brushed to create a soft, fuzzy surface, which makes it warmer and more matte.
Is a higher Super number better?
Not always. Higher numbers feel softer but wrinkle and wear faster. Super 100s-130s is best for suits you wear often.
Is merino wool good for suits?
Yes. Merino is fine and soft, and most quality suiting wool is spun from merino fibres.
