The Indispensable Fashion Glossary: More Than Just a Dictionary

With clear, concise definitions of hundreds of terms related to clothing, fabrics, production, and more, our glossary is the perfect resource for designers, manufacturers, and fashion enthusiasts. But why is such a resource so critical? The fashion ecosystem is a multidisciplinary orchestra. A designer’s vision must be translated by a pattern maker into technical specifications, communicated to a sample machinist, understood by a fabric sourcing agent, and finally executed by a production line team across potentially multiple countries. Each of these roles operates within its own lexical subset.

• For Designers: Understanding terms like dart, grain line, and bias is fundamental to creating functional, well-fitting patterns.
• For Manufacturers & Production Managers: Terms like CMT (Cut, Make, Trim), FOB (Free on Board), and lead time are the bedrock of costing, scheduling, and logistics.
• For Buyers & Retailers: Knowing the difference between woven and knit, or handfeel and drape, directly impacts product selection, pricing, and customer satisfaction.
• For Enthusiasts & Students: This knowledge demystifies the craft, deepens appreciation for construction, and is the first step toward professional competency.

This glossary provides a comprehensive collection of essential terms used in apparel design and manufacturing to help professionals navigate the industry with confidence. It’s designed as a living reference, a tool to consult at every project stage to ensure everyone is literally and figuratively on the same page.

The Monumental Scale of Apparel Manufacturing: Why Terminology Matters

Apparel manufacturing is a complex and huge lengthy process. It’s rarely a simple, linear journey from idea to garment. It’s a multi-phase, global operation involving design, technical design, fabric and trim sourcing, pattern making, sampling, costing, production planning, cutting, sewing, finishing, quality control, and logistics. Thousands of terminologies are used in the garment industry to operate production and business efficiently. Each phase introduces its own lexicon.

Consider the journey of a single style:

1. Design & Tech Pack: A designer specifies a silhouette, fit type (e.g., slim, regular), and fabric construction. A technical designer then creates a tech pack with specs (measurements), callouts, and construction details.
2. Sourcing: A sourcing manager seeks fabrics with specific GSM (Grams per Square Meter), thread count, and finishes (e.g., water repellent, brushed). They negotiate MOQs (Minimum Order Quantities) and incoterms.
3. Pattern & Sample: A pattern maker translates the 2D sketch into a pattern, using notches, drills, and grain lines. The sample machinist then creates a fit sample, production sample, or sew-by-sample, noting any fit issues or construction challenges.
4. Production: The factory manager plans cutting tickets, manages line balancing, and tracks efficiency (e.g., SAM – Standard Allowed Minutes). The sewing line uses terms like basting, underlining, and topstitching.

As a textile and apparel professional, it is very essential to know those apparel terms or glossary for proper communication. A single misunderstood term—confusing fusing (applying interfacing with heat) with interfacing (the stabilizer itself)—can ruin an entire batch of collars. This shared language is the glue that holds the fragile, high-stakes process together.

Navigating the Financials: Costing & Pricing Terminology

In the world of fashion production, understanding costing and pricing terms is essential for success. Profitability is determined long before a garment hits the rack; it's baked into the numbers during the costing phase. Whether you're a designer, manufacturer, or retailer, knowing these terms can help you navigate the complexities of the industry and make informed decisions.

Key Costing & Pricing Terms:

• FOB (Free on Board): The price quote includes all costs up to and including the loading of goods onto the vessel at the named port of shipment. The buyer assumes responsibility and cost for marine freight, insurance, etc.
• CMT (Cut, Make, Trim): A common manufacturing service where the factory is provided with all materials (fabric, trims) and is only responsible for cutting, sewing, and adding final trims like buttons and labels.
• Target Cost: The maximum allowable cost to produce a garment to achieve a desired profit margin at the intended retail price.
• Consumption: The amount of fabric (often in yards or meters) required to make one garment, including fabric wastage or shrinkage allowance.
• Marker Efficiency: The percentage of fabric utilized on a cutting marker (the diagram of pattern pieces laid out on fabric). Higher efficiency means lower cost per garment.
• Landing Cost: The total cost of a product once it has arrived at the buyer’s destination port, including FOB price, freight, insurance, duties, and taxes.
• Wholesale vs. Retail Price: The wholesale price is what a retailer pays the brand/manufacturer. The retail price (MSRP) is what the end consumer pays. The keystone markup traditionally doubles the wholesale price to set retail.

Practical Tip: Always request a detailed cost sheet from your manufacturer. It should break down costs per unit: fabric, trim, labor, overhead, and profit. This transparency allows for negotiation and identifies areas for cost reduction without sacrificing quality.

The Heart of Construction: A Glossary of Sewing Terms

This glossary contains terms used in sewing, tailoring, and related crafts. This is where the abstract design becomes tangible. Understanding these terms is crucial for evaluating sample quality, writing clear instructions, and troubleshooting production issues.

Fundamental Sewing Techniques & Components:

• Seam: The line where two pieces of fabric are joined by stitching.
• Seam Allowance (SA): The width of fabric between the seam line and the cut edge. Standard SA varies (e.g., 5/8" for garments, 1/4" for crafts).
• Basting: Temporary, long stitches used to hold pieces in place before final sewing. Also called tacking.
• Topstitching: Stitching visible on the right side (face) of the garment, often for decorative effect or to secure seams (e.g., on jeans or collars).
• Underlining: A separate layer of fabric (often interfacing or lightweight lining) sewn to the wrong side of the fashion fabric to add body, stability, or opacity.
• Facing: A piece of fabric used to finish the raw edges of a garment opening (neckline, armhole, hem) and provide a clean interior finish. It can be sewn-in or applied.
• Lining: A separate inner layer of fabric that provides a smooth interior finish, adds warmth, and hides seam construction.
• Interfacing: A material (woven, non-woven, or knit) fused or sewn to the wrong side of a fabric to add stiffness and shape to areas like collars, cuffs, and waistbands. Comes in fusible (iron-on) or sew-in.
• Dart: A tapered fold in a pattern piece, sewn to provide shape and remove excess fabric. An overlapped/folded over and sewn piece of fabric that’s meant to add dimension and shape to a garment is the literal definition of a dart. Darts can be added if your jacket or shirt fits relatively well and you want a more defined shape without taking in/removing fabric. They are fundamental to fitting garments to the body’s curves (bust, waist, shoulders).

Advanced Construction Terms:

• Grain: The direction of the yarns in a woven fabric. Lengthwise grain (warp) runs parallel to the selvage. Crosswise grain (weft) runs perpendicular. Cutting on grain is essential for proper drape and stability.
• Bias: The 45-degree angle to the warp and weft. Fabric cut on the bias has more stretch and drape beautifully (e.g., bias-cut skirts). True bias is exactly 45 degrees.
• Notch: A small V-shaped cut on the seam allowance of a pattern piece used to match pieces accurately during sewing (e.g., shoulder notch to shoulder notch).
• Drill/Notch Mark: A small hole or clip in the pattern seam allowance to mark a point for placement of details like pockets, buttons, or pleats.
• French Seam: A refined seam where the raw edges are completely enclosed, used for sheer or delicate fabrics. The seam is sewn, trimmed, and then sewn again.
• Flat-Felled Seam: A very strong, flat seam where the raw edges are encased, common on denim (e.g., jeans seam) and sportswear.
• Gather: A technique to reduce the length of a fabric edge so it can be attached to a shorter piece (e.g., sleeve cap to armhole). Created by sewing long, loose stitches and pulling the thread.
• Ease: The amount of space within a garment for movement. Wearing ease is for comfort. Design ease is for style (e.g., an oversized silhouette). Pattern pieces will have ease built into their measurements relative to body measurements.

Beyond Sewing: Fabric & Textile Manufacturing Terms

For terms used in the creation or manufacturing of textiles, including spinning, knitting, weaving, and individual fabrics and finishing processes, see glossary of textile manufacturing. The choice of fabric dictates the garment's behavior, care requirements, and cost. A designer must understand the origin of their material.

Fabric Construction Basics:

• Woven: Fabric made by interlacing two sets of yarns at right angles (warp and weft). Examples: poplin, denim, twill. Stable, with little stretch unless made with elastane.
• Knit: Fabric made by interlocking loops of yarn. Examples: jersey, rib, interlock. Naturally stretchy and flexible.
• Non-Woven: Fabric made by bonding fibers together (e.g., felt, interfacing, some medical textiles). No yarn structure.
• Selvage/Selvedge: The tightly woven edge of a fabric that runs parallel to the warp yarns. It doesn’t fray. Pattern pieces should never be cut from the selvage.
• Yarn-Dyed: Fabric where the yarns are dyed before weaving or knitting (e.g., gingham, tweed). Creates patterns like stripes or checks.
• Piece-Dyed: Fabric dyed after it has been woven or knitted into a solid color.

Common Fabric Finishes:

• Sanforized: A pre-shrinking treatment for fabrics, especially cotton, to minimize shrinkage after laundering.
• Brushed: Fabric (often fleece or flannel) that has been treated with a brush to raise the fibers, creating a soft, fuzzy surface.
• Mercerized: Cotton treated with a caustic soda solution under tension to increase luster, strength, and dye affinity.
• Water Repellent/Resistant: A finish (often a coating or membrane) that causes water to bead up and roll off.
• Stretch: Fabric with added elastane (e.g., Lycra®, Spandex) yarns to provide recovery and flexibility.

For terms used in dyeing, see glossary of dyeing terms. This includes processes like piece dyeing (dyeing finished fabric), yarn dyeing, and stock dyeing (dyeing raw fibers), as well as specific dye types (reactive, disperse, acid) and techniques (batik, tie-dye, screen printing).

Putting It All Together: From Concept to Closet

Let’s trace a hypothetical garment using this terminology. A designer creates a tech pack for a woven cotton poplin shirt with a bias-cut skirt attached. The spec calls for a 5/8" seam allowance, French seams on the armholes for a clean finish, and darts at the bust and back waist for shaping.

The sourcing agent sources sanforized poplin at a GSM of 120, with a marker efficiency target of 85%. The pattern maker creates the pattern on grain, marking notches at the shoulder and sleeve cap. The sample is made as a fit sample; the sample machinist notes that the bias skirt needs a lining to prevent slipping.

During costing, the consumption is calculated: 2.2 yards of fabric per unit. The factory quotes a CMT price. The buyer calculates the landing cost and sets the wholesale and retail prices.

On the production line, operators baste the darts, underline the collar with fusible interfacing, and execute the flat-felled seam on the side seams for durability. The finished goods undergo quality control for stitch length, topstitching uniformity, and fit against the golden sample.

This example illustrates how these terms aren't isolated; they form a connected workflow. A change in fabric (from woven to knit) alters the seam type needed (a coverstitch might replace a flat-felled seam for stretch). A request for a gathered sleeve head instead of a fitted one impacts the pattern shape and ease calculation.
