The Retailer's Glossary of Suit & Shirting Fabrics

The Retailer's Glossary of Suit & Shirting Fabrics

Customers don't buy "a suit." They buy how it feels, how it drapes, and whether it still looks sharp at 6 p.m. That all comes down to fabric — and if you're buying wholesale, fabric literacy is margin literacy. Here's a practical glossary of the fibers, blends, and weaves you'll see in wholesale menswear.

Natural fibers

Wool. The king of suiting. Naturally breathable, wrinkle-resistant, and with a drape nothing synthetic quite matches. In wholesale you'll see 100% wool at the premium end (look for Super numbers — Super 110s, 120s — which describe fiber fineness, not quality per se). Wool suits are the backbone of any serious suiting assortment.

Cotton. The dress-shirt default. Breathable, soft, and easy to care for. In suiting, cotton gives a more casual, matte finish — great for warm-weather and business-casual assortments. Cotton shirts in white and light blue are the highest-velocity items in most stores.

Linen. The summer specialist. Unmatched breathability with a distinctive texture — and yes, it wrinkles, which is part of the look. Linen shirts and unstructured suits sell in a tight seasonal window; buy accordingly and don't carry them into fall.

Manufactured fibers

Polyester. Durable, wrinkle-resistant, and inexpensive. On its own it can feel slick and trap heat, but in blends it adds resilience and shape retention at a friendly price point. Most entry-price wholesale suits contain polyester — know the percentage, because it drives both the hand-feel and the retail price.

Viscose / rayon. A semi-synthetic made from wood pulp. Adds softness and drape to blends and is commonly used in suit linings. It improves how a garment hangs without adding much cost.

Blends

Blends exist to get the best of both worlds: the feel of natural fibers with the durability and price of synthetics. A wool-polyester blend, for example, keeps much of wool's drape while resisting wrinkles better and costing less. A cotton-polyester shirt stays crisp through a long day.

When evaluating a blend, two numbers matter: what's in it and in what proportion. A "wool blend" that's 10% wool is a very different garment from one that's 80% wool. Ask for the composition — reputable wholesalers list it.

Stretch fabrics: 2-way vs 4-way

Stretch is one of the biggest selling features in modern wholesale menswear, and the terms get thrown around loosely. Here's what they mean:

2-way stretch fabrics stretch in one direction (usually horizontally). They add comfort across the shoulders and chest — enough for most suit and shirt buyers to feel the difference.

4-way stretch fabrics stretch both horizontally and vertically. The result is a garment that moves with the body in every direction — the reason performance dress shirts (like Vitarelli's 4-way stretch lines) have become best sellers. For retailers, "4-way stretch" is a genuine selling point to put on the ticket: customers feel it in the fitting room in ten seconds.

Weaves worth knowing

Twill. Diagonal rib pattern. Durable, drapes well, resists wrinkles — the workhorse suiting weave.

Sharkskin. A smooth basket or twill weave with a subtle two-tone shimmer. A classic for formal and evening suits.

Birdseye / nailhead. Tiny dotted patterns woven into the cloth. Reads as solid from a distance, adds texture up close — a smart choice for business suits.

Plain weave / poplin. The standard dress-shirt weave: smooth, crisp, and clean. Broadcloth is its dressier cousin.

What to stock by season

• Year-round core: wool and wool-blend suits in navy, charcoal, and black; cotton dress shirts in white and light blue.
• Spring/summer: linen shirts, cotton suits, lighter colors and lighter weights.
• Fall/winter: heavier wool suits, deeper tones, textured weaves.

A note on care (pass it to your customers)

Most suits are dry clean only — over-cleaning wears them out faster than wearing them does. Shirts are machine washable; hang dry or tumble low, and a quick steam keeps them sharp. Put care basics on a hang tag or your product pages — it cuts returns and builds trust.

Stock what sells

Fabric knowledge pays off twice: you buy better, and your staff sells better. A salesperson who can explain why the 4-way stretch shirt costs more than the basic cotton one closes more sales.
