Before the Factory — Fabric Matters Most
Every quality problem in a finished shirt can be traced to one of two sources: the fabric, or the making. The industry aphorism is accurate — you cannot make a good shirt from bad fabric, but you can easily ruin good fabric with poor making. The sequence described here assumes you start with fabric that has been correctly specified, sampled, tested, and approved. Skipping that foundation makes every subsequent step uncertain.
The main components of a woven dress shirt requiring separate fabric or material inputs are: front body panels, back body panel, collar, collar band (separate from collar in most constructions), cuffs, sleeve panels, placket (front button band), and sometimes a yoke across the upper back. Each of these components may have different grain requirements, and in striped or checked fabrics, matching across seams is an additional precision requirement that significantly affects fabric yield and cutting time.
The Production Sequence — Step by Step
Step 01
Fabric Inspection
On receipt at the factory, fabric rolls are inspected against the approved pre-production sample. The inspection checks shade (against the approved standard under D65 light source), GSM, width, hand feel, and visible fabric defects. The standard used is the 4-point system, in which defects are assigned penalty points based on their size. A fabric lot scoring more than 28 penalty points per 100 linear metres is typically rejected or quarantined for review. Shade variation between rolls — metamerism — is checked under both daylight and artificial light, as some dye combinations shift shade significantly under different light sources. This step is non-negotiable in professional garment manufacturing. Factories that skip it discover shade and quality problems after cutting, at which point the loss is far greater.
Step 02
Pattern Making and Grading
The approved garment specification — the tech pack — is translated into a set of paper or digital pattern pieces. Each pattern piece represents one component of the shirt and includes seam allowances, grain line markings, notches for alignment, and size labels. Grading is the process of scaling the base size pattern up and down to produce the full size range. In professional production, pattern making and grading are done digitally using CAD software. The accuracy of the pattern directly determines whether the finished shirt matches the design specification — an error of 2mm in a collar pattern, multiplied across 10,000 units, is an expensive problem.
Step 03
Marker Making
A marker is the arrangement of all pattern pieces for a given size ratio across the width of the fabric, optimised to minimise fabric wastage. Marker making is a technical skill — for a standard shirt, fabric utilisation of 80–85% is considered efficient; utilisation below 75% indicates poor marker making or an inefficient size ratio. For fabrics with a nap, directional print, or stripe that requires matching, marker making is significantly more complex and fabric consumption increases accordingly. Stripe-matched shirts can add 15–25% to fabric consumption versus a plain fabric of identical construction.
Step 04
Fabric Spreading and Cutting
Fabric is spread in multiple plies — layers — on the cutting table, with each ply aligned precisely at the edges and ends. The number of plies depends on the fabric weight, the cutting method, and the order quantity. For a 120 GSM shirting, 60–80 plies is typical with a straight knife cutter. The marker is placed on top and the cutting proceeds along the pattern outlines. In modern factories, this is done with computer-controlled straight knife or band knife cutting systems. For high-precision components like collars and cuffs, die cutting — using a steel rule die — is preferred for consistent accuracy. Cut panels are then bundled by component and size, ticketed, and passed to the stitching section.
Step 05
Interlining Application
Before stitching begins, interlining is applied to certain components — primarily the collar, collar band, cuffs, and front placket. Interlining is a support fabric that gives body and structure to these components. It is typically a woven or non-woven fabric with a heat-activated adhesive on one side. In industrial production, interlining is fused to the fabric components using a flat-bed fusing press at controlled temperature, pressure, and dwell time settings specific to the interlining and shell fabric combination. Incorrect fusing — wrong temperature, insufficient dwell time, inadequate pressure — results in delamination in wash, which is one of the most common quality failures in shirts at all price points.
Step 06
Sub-Assembly — Collar, Cuffs, Placket
The shirt is not assembled in one pass. It is built from sub-assembled components that are then joined. The collar is made by stitching the top collar to the under-collar, trimming, turning, and topstitching. The collar band is similarly assembled and attached to the completed collar. Cuffs are constructed in a parallel process. The front placket is folded, stitched, and pressed. These sub-assemblies are produced in dedicated work stations before the main assembly line. The quality of sub-assembly — collar point symmetry, cuff corner sharpness, placket straightness — has the most visible impact on the premium appearance of the finished shirt.
Step 07
Main Assembly — Body Construction
The shirt body is assembled through a sequence of operations: shoulder seam joining, yoke attachment, sleeve attachment, side seams and sleeve seams (run together in one continuous operation on quality shirts), hem stitching, and sleeve placket opening. The order of operations is engineered for efficiency and quality — the shoulder-to-sleeve approach used in quality shirt manufacturing produces a cleaner armhole than the alternative sleeve-first approach used in volume production. Seam types vary by application — plain seams, flat-felled seams (which encase the raw edge on the inside for durability), and French seams each have different appearances, durability characteristics, and production speeds.
Step 08
Collar and Cuff Attachment
The assembled collar with band is attached to the shirt neckline. This is one of the most technically demanding operations in shirt making — the collar must sit symmetrically, the collar band must join precisely at the front opening, and the neckline seam must be consistent in width without visible waviness. Attachment is typically done in two passes: a first stitch joining collar band to neckline, and a second topstitch or under-stitch to secure and finish the inner edge. Cuffs are similarly attached to the sleeve openings. The precision of collar and cuff attachment is the first thing a quality controller and an experienced buyer look at when assessing shirt construction.
Step 09
Buttonholes and Buttons
Buttonholes are made using an eyelet buttonhole machine (for shirts, typically a horizontal keyhole or straight buttonhole). Button placement is marked and buttons are stitched using an automatic button sewing machine, with a thread shank of appropriate length for the fabric weight. On quality shirts, the collar stand button is typically a slightly smaller diameter than the body buttons. Buttons are checked after stitching for security — a pull force of at least 40 Newtons is the standard minimum for button attachment strength. In export production, button standards are specified by the buyer and include composition (polyester, natural shell, corozo), diameter, hole count, and colour match to the fabric.
Step 10
Finishing — Pressing and Ironing
The completed shirt is pressed using a combination of a buck press (for collar and cuffs) and a hand iron with a sleeve board and body board. Steam ironing is used throughout. The collar is the most labour-intensive pressing operation — points must be sharp, the roll line must be natural, and the overall collar must be symmetrical when laid flat. Cuffs are pressed flat and square. The shirt body is pressed on a form or body board to give it its presentation shape. In volume production, automated shirt pressing tunnels handle the body, but collar and cuff pressing remains a manual operation at all quality levels. The quality of pressing is what makes a shirt look premium in the pack and on the hanger at point of sale.
Step 11
Quality Control and Inspection
Finished shirts are inspected against the approved sealed sample and the buyer's quality standard. End-line inspection checks measurements against the spec sheet, construction quality (seam integrity, stitch density, collar and cuff symmetry, button security), appearance (shade, pressing quality, absence of stains or damage), and trim compliance (labels correctly positioned and stitched, care labels accurate). The standard inspection methodology is AQL (Acceptable Quality Level) sampling — statistically defined sample sizes from each production lot, with defect counts determining acceptance or rejection. AQL 2.5 is the standard for most garment buyers; AQL 1.0 is used for premium and luxury production.
Step 12
Packing and Dispatch
Approved shirts are folded to the buyer's specified presentation fold, pinned (collar pin, body pins, sleeve pins at specified positions), inserted into polybags, and packed into cartons at the buyer's specified packing ratio. Export cartons are marked with style number, colour, size breakdown, quantity, carton number, gross and net weight, and destination. For domestic shipment, packing is simpler but the same fold and presentation standards apply. At this stage, the shirt has typically passed through 25 to 40 individual operations from fabric receipt to dispatch, with each operation capable of introducing a defect that reduces the finished garment's quality or commercial value.
Why This Matters for Brands and Buyers
Understanding the production sequence is not just academic knowledge. It directly informs how you communicate with manufacturers, how you evaluate factory capability, how you set lead times, and how you price your product honestly.
A shirt that costs Rs. 180 to make at a volume factory in Tirupur and a shirt that costs Rs. 650 to make at a quality factory in Mumbai or Bengaluru are not the same product — and the differences are visible at every step described above. The collar flatness, the fusing integrity, the button attachment, the pressed presentation, the seam consistency — these are the physical expressions of the time, skill, and discipline invested at each workstation.
The fabric is the foundation. But the making is where a shirt becomes what it is.
On fabric's role in this process: The fabric choice affects almost every step in production. A fabric that frays excessively complicates cutting and seam finishing. A fabric with high shrinkage requires pre-shrinking before cutting or pattern adjustments. A fabric with poor dimensional stability causes seam puckering. A fabric with inconsistent shade creates problems at inspection. Good fabric sourcing is not just a quality decision — it is a production efficiency decision. This is why professional garment manufacturers prefer to work with fabric suppliers who provide consistent, documented, tested material.
