Skirt Manufacturing Process

Skirts have fewer operations than trousers and more ways to go wrong visually. There is no second leg to compare against, so any imbalance in the pattern shows immediately: a hem that rises at the back, a side seam that swings forward, a pleat set that opens unevenly. This page follows the construction and points out where balance is won or lost.

Silhouette decides everything downstream

Pattern balance

Balance is the relationship between the front and the back of the pattern, and it is what makes a skirt hang level on a body rather than on a table. The back usually needs slightly more length and shaping than the front, because the body is not symmetrical front to back.

• Waist to hip. The measurement relationship that decides whether the skirt sits smoothly or pulls diagonal creases from the hip.
• Front and back length. State them separately. A hem specified as one figure will usually rise at the back on a fitted skirt.
• Hem sweep. The finished circumference, which decides walking room on straight shapes and drape on flared ones.
• Grain. On flared and circle skirts, panels behave differently on straight grain and on bias, and the hem drops unevenly if the grain is not controlled.

Fabric

Pleats and how they are set

Pleating is an area where fibre choice has a direct consequence, and it is worth understanding before a design is finalised.

• Pleat type. Knife pleats all fold in one direction, box pleats fold away from each other, and inverted pleats fold towards each other. Each gives a different volume and a different fabric consumption.
• Pleat depth and spacing. Specify both as measurements. They determine how much fabric the skirt consumes, which is often more than buyers expect on a fully pleated style.
• Setting on synthetics. Polyester and polyester-rich fabrics can be heat set, so the pleats are effectively permanent and survive washing.
• Setting on natural fibres. Cotton, viscose and wool do not hold heat-set pleats in the same way. Pleats in those fabrics are usually stitched down for part of their length, or accepted as requiring pressing after washing. Say which you expect.
• Stitched-down pleats. Held with topstitching from the waist to the hip, which keeps the skirt flat over the body and lets the pleats open below.

Waist treatment and closure

• Separate waistband. Interlined so it holds its shape, straight or contoured. A contoured band sits better on a fitted skirt.
• Facing instead of a band. A cleaner line at the waist, faced on the inside, used on tailored and minimal designs.
• Elasticated waist. Full elastic in a casing for pull-on styles, or elastic at the back only with a flat front for uniform and service skirts.
• Closure. A concealed zip at the centre back is the tailored standard; a side zip is common on fitted styles; a wrap uses ties or a fastening; a pull-on style needs no closure at all but requires enough stretch or sweep to pass the hip.
• Zip quality. A concealed zip must lie flat and invisible, which depends on both the zip and the sewing. It is one of the details buyers notice most on a sample.

Lining

Lining is specified for three reasons: opacity, comfort against the skin, and to help the shell hang without clinging. It is not automatic, and it should be a deliberate decision rather than an assumption.

• Choose the lining fabric for slip and breathability, not only for colour.
• The lining is normally cut slightly shorter than the shell so it never shows at the hem.
• It is usually attached at the waist and left hanging free at the hem, so the two layers can move independently.
• On a slit or vent, decide whether the lining follows the opening or stops above it.
• For sports skirts, the inner layer is a functional short or legging rather than a lining, with its own fabric and fit.

Slits, vents and hems

A straight skirt needs walking room, provided by a slit or a vent. Both need a reinforcement at the top of the opening, because that is the point where the fabric tears when the wearer takes a long stride. State the height of the opening as a measurement.

Hem construction follows the shape. A straight hem can take a deep turned hem, which adds weight and helps it hang. A curved or flared hem needs a narrow hem, because a deep fold cannot lie flat on a curve. A blind hem gives an invisible finish on tailored skirts; a machine-stitched hem is faster and visible.

Assembly sequence

1. 1Panels are cut on grain, with lining cut at the same time where used.
2. 2Darts are formed and pleats are set or stitched down.
3. 3Side and back seams are closed, leaving the closure opening.
4. 4The zip is inserted, or the elastic casing is prepared on pull-on styles.
5. 5The waistband or facing is attached and finished.
6. 6The lining is assembled and attached at the waist.
7. 7The skirt is hung so any bias sections settle, then the hem is levelled.
8. 8The hem is finished, the garment is pressed, measured and inspected.

Pressing

Skirts are pressed during construction as well as at the end: seams pressed open, waistbands and facings pressed as they are built, pleats set and pressed. On a pleated skirt the pressing is the product, and pressing quality is a specification item rather than a finishing detail.

Quality control: skirt-specific checks

What to put in a skirt tech pack

• Silhouette, with a sketch and reference images.
• Fabric: composition, weave or knit structure, weight, and lining fabric where used.
• Waist, hip, front length, back length and hem sweep, with tolerances.
• Waist treatment: band, facing or elastic, with height and interlining.
• Closure: type, position and length.
• Pleats: type, depth, spacing, and whether they are heat set or stitched down.
• Slit or vent: position, height and reinforcement.
• Lining: fabric, length relative to the shell, and attachment.
• Hem: type and depth.
• Inner short or legging where the skirt is a sports style, with its own fabric and fit.
• Pressing requirements, particularly for pleated styles.
• Labels and packing.

Sampling

Sample on a body, and look at the side seam from the side rather than the front. A skirt that measures correctly can still swing forward if the balance is wrong, and that is invisible flat. Walk in it: a straight skirt with an under-specified slit is comfortable standing still and unwearable in practice.

For pleated styles in natural fibres, wash-test the sample and look at the pleats afterwards. It is the reliable way to know whether the pleats will survive the customer's laundry.
