Common Seam Types in Outerwear and Knitwear
The selection of a seam is a foundational decision in garment construction, directly influencing a garment's durability, comfort, and appearance. For outerwear and knitwear, which are often subjected to stress and require specific material handling, the choice of seam is particularly critical. The following table outlines several common seam types, their construction, and their typical applications in these categories.
| Seam Type | Description | Common Applications |
|---|---|---|
| Plain Seam | The most basic seam, created by sewing two pieces of fabric together. The seam allowance is then pressed open or to one side. It is versatile and can be used with a wide range of fabrics and garment types. However, its simplicity means that the raw edges of the fabric are exposed, necessitating a separate finishing technique to prevent fraying, especially in unlined jackets or garments made from loosely woven materials. The quality of a plain seam is therefore also dependent on the quality of its finish. | Used in a wide variety of garments, but requires a separate finishing technique on the raw edges to prevent fraying, especially in unlined jackets. |
| French Seam | A seam within a seam, which encloses the raw edges of the fabric. This is achieved by first sewing a seam with the wrong sides of the fabric together, then trimming the seam allowance and pressing it to one side. The fabric is then folded with the right sides together, and another seam is sewn, enclosing the raw edges of the original seam. It is a time-consuming but very durable and neat finish, creating a clean and polished look on both the inside and outside of the garment. | Ideal for lightweight and delicate fabrics, such as those used in lining, but can be too bulky for heavier wools or leathers. |
| Flat-Felled Seam | A very strong and durable seam where the raw edges are folded and stitched flat. It is visible from both the inside and outside of the garment. This seam is created by placing one fabric edge over the other, folding the top edge under, and then stitching both edges down. This creates two visible rows of stitching. It is exceptionally strong and resistant to stress, making it a popular choice for utilitarian garments. | Commonly used for outerwear and garments made from heavy-duty fabrics like denim and canvas. It is a hallmark of high-quality casual and workwear. |
| Lapped Seam | Created by overlapping two pieces of fabric and sewing them together. This seam is often used for materials that do not fray, such as leather and suede, as the raw edges are not enclosed. The quality of a lapped seam is dependent on the precision of the stitching and the quality of the thread used. | Frequently used in leather and suede garments, as well as for attaching patch pockets. |
| Bound Seam | The raw edges of the seam allowance are enclosed in a fabric binding. This technique provides a neat finish and can also be a decorative element. The binding can be made from the same fabric as the garment or a contrasting fabric for a design detail. A bound seam is a sign of a well-finished garment, as it requires extra time and material to create. | Often used on unlined jackets and coats to create a clean, finished interior. It is also used on hems and cuffs. |
| Welt Seam | A seam where one edge of the seam allowance is cut shorter than the other, and the wider allowance is folded over the narrower one and stitched down. This creates a raised, decorative effect on the outside of the garment. It is a strong seam that is less bulky than a flat-felled seam. | A strong seam that is less bulky than a flat-felled seam, often used in tailoring and for reinforcing seams in outerwear. |
| Superimposed Seam | Two or more pieces of fabric are laid on top of each other and stitched together near the edge. This is a broad category that includes the plain seam. The ISO 4916 standard defines this as Class 1, and it is the most common type of seam construction. | The most common seam class, used for a vast array of applications in all types of garments. |
| Edge Finishing Seam | This seam is used to finish the edge of a single piece of fabric, such as a hem or a facing. This is not a construction seam in the sense of joining two pieces of fabric, but it is a critical element of garment construction. The ISO 4916 standard defines this as Class 6. | Essential for all garments to prevent fraying and to provide a neat, durable edge. |
Stitching Density and Durability
The density of stitching, measured in stitches per inch (SPI), is a direct indicator of the time and thread invested in a garment's construction, and it has a significant impact on seam strength and durability. A higher SPI generally results in a stronger, more durable seam, as the force is distributed over more stitches. This is because a greater number of stitches per inch means that the load is spread more evenly, reducing the stress on any single point. However, the optimal SPI is dependent on the fabric type; a high SPI on a delicate fabric can damage the material by creating too many perforations, which can weaken the fabric and lead to tearing. Conversely, a low SPI on a heavy fabric can result in a weak seam that is prone to failure under stress.
| Fabric Type | Recommended SPI | Application Examples |
|---|---|---|
| Lightweight Wovens | 10-14 | Shirts, Blouses, Linings |
| Mediumweight Wovens | 8-12 | Trousers, Skirts, Light Jackets |
| Heavyweight Wovens | 6-10 | Denim, Canvas, Heavy Coats |
| Lightweight Knits | 12-16 | T-Shirts, Underwear |
| Medium to Heavy Knits | 10-14 | Sweaters, Fleece |
| Leather and Suede | 6-10 | Jackets, Trousers, Skirts |
As a general rule, a higher stitch count is a sign of a well-made garment, but it must be appropriate for the fabric. For example, a fine cashmere sweater will have a higher SPI than a rugged leather jacket, and both are correct for their respective materials. A discerning eye can learn to recognize the appropriate stitch density for different fabrics, and this is a key aspect of evaluating garment quality.
Evaluating Construction Quality
A comprehensive evaluation of a garment's construction quality involves a close examination of its seams, hems, and finishing details. These elements, when executed with precision, contribute to the garment's overall longevity and aesthetic appeal.
Examining Seams
When inspecting a garment's seams, consider the following:
- Consistency: The stitches should be of a consistent length and tension. Inconsistent stitching can be a sign of poor quality control and can lead to seam failure. Look for any skipped stitches or areas where the tension is too loose or too tight, as these are all signs of a poorly constructed garment.
- Stitch Type: The stitch type should be appropriate for the fabric and the seam's location on the garment. For example, a chain stitch is more elastic than a lockstitch and is therefore better suited for seams that require some stretch, such as in knitwear. A lockstitch, on the other hand, is more secure and is a better choice for woven fabrics.
- Seam Finish: The raw edges of the seam allowance should be finished to prevent fraying. Common finishing techniques include serging, binding, and flat-felling. The choice of finish should be appropriate for the fabric and the garment's overall quality. An unfinished seam on a woven fabric is a clear sign of a poorly made garment.
Hems and Finishing
The hem is the finished edge of a piece of fabric in a garment, which has been turned under and sewn. A well-executed hem is a hallmark of a quality garment.
- Evenness: The hem should be even and parallel to the floor when the garment is worn. An uneven hem is a sign of sloppy workmanship.
- Flatness: The hem should lie flat and not be puckered or twisted. A puckered hem is often the result of incorrect tension during sewing.
- Finishing: The raw edge of the hem should be neatly finished to prevent fraying. Common hem finishes include a simple turned hem, a blind hem, and a bound hem. The choice of finish will depend on the fabric and the style of the garment.
Other finishing details to examine include the attachment of buttons and the construction of buttonholes. Buttons should be securely attached with a sufficient number of stitches, and the thread should be neatly finished. Buttonholes should be neatly stitched and appropriately sized for the buttons. A poorly made buttonhole can be a sign of a garment that has been rushed through production.
Frequently Asked Questions
What is the difference between a seam and a stitch?
A stitch is the single loop of thread that is used to join fabric, while a seam is the line of stitches that joins two or more pieces of fabric together. In essence, seams are made of stitches. The type of stitch used, along with the thread and the fabric, will determine the properties of the seam.
Why is a French seam considered a high-quality finish?
A French seam is considered a high-quality finish because it is a time-consuming and skilled technique that results in a very neat and durable seam. The raw edges of the fabric are completely enclosed, which prevents fraying and creates a clean, professional appearance on both the inside and outside of the garment. This level of attention to detail is a hallmark of a well-made garment.
How can I tell if a garment has a high stitch density?
You can determine the stitch density of a garment by counting the number of stitches within a one-inch section of a seam. A higher number of stitches indicates a higher stitch density. While you may not carry a ruler with you when shopping, you can train your eye to recognize the difference between a garment with a high stitch density and one with a low stitch density. Over time, you will develop a feel for what constitutes a quality stitch density for different types of fabrics.
What are some other signs of a well-made garment?
In addition to the quality of the seams, stitching, and hems, there are other details to look for. These include the quality of the fabric itself, the matching of patterns at the seams, the quality of the lining, and the overall fit of the garment. A well-made garment will be the sum of many small, well-executed details.
Is a higher price always an indicator of better quality?
While there is often a correlation between price and quality, this is not always the case. A higher price may be due to branding, marketing, or other factors that have nothing to do with the quality of the garment's construction. By learning to evaluate the construction of a garment yourself, you can make more informed purchasing decisions and not be swayed by price alone.
