A good fit in a garment is a delicate balance of several factors working together.
1. Clear Indication of the Point of Measurement
-
Accuracy from the Start: Starting with accurate measurements is fundamental to achieving a good fit. It means clearly defining where each measurement is taken (e.g., high bust, natural waist, hip, etc.). Standardized measurement charts and guides are essential for consistency.
-
Measurement Charts and Size Systems: Accurate and consistent body measurement charts are essential. These charts provide the basis for creating size systems (e.g., XS, S, M, L) and ensure that garments are graded correctly across different sizes.
-
Tolerance: Establish acceptable tolerances for measurements. The permissible deviations in measurements throughout the manufacturing process are defined by tolerances. It accounts for minor inconsistencies in manufacturing.
2. Design Aligned with the Right Fabric
-
Fabric Properties: Different fabrics have different properties (e.g., stretch, drape, weight, thickness). The design must be compatible with the chosen fabric. A fitted design in a non-stretch fabric will have different fit implications than the same design in a stretch knit.
-
Drape and Movement: The drape (how it hangs) and its ability to move with the body are crucial for comfort and aesthetics. A fabric with a good drape will enhance the lines and allow for comfortable movement.
-
Fabric Weight and Structure: The weight and structure of the fabric will affect how it interacts with the body. A heavy fabric may require more structured design elements to support its weight, while a lightweight fabric may require less structure.
3. Precision in Pattern Development
-
Pattern Accuracy: Accurate pattern drafting or digital pattern making is essential. Even tiny errors in the pattern can lead to significant fit issues in the final garment.
-
Grainline: The grainline (the direction of the lengthwise yarns) must be correctly marked on the pattern and followed during cutting. Incorrect grain can cause twisting or distortion in the finished garment.
-
Ease: Ease is the amount of extra fabric added to a garment for comfort and movement. There are different types of ease:
-
Wearing ease: The minimum amount of ease needed for basic movement.
-
Design ease: Additional ease added for aesthetic or stylistic purposes.
-
Dart Placement and Shape: Darts shape fabric around curves. Correct dart placement and shape are essential for a smooth and flattering fit.
4. Skilled and Meticulous Sewing
-
Consistent Seam Allowance: A consistent seam allowance during sewing is crucial for accurate fit. Inconsistent seam allowances can alter the intended size and shape of the garment.
-
Seam Construction: Different seam types (e.g., plain seam, French seam, flatlock seam) have different properties and are suitable for various fabrics and designs. Choosing the seam construction for both fit and durability.
-
Matching Notches and Markers: Notches and other markers on the pattern align pattern pieces during sewing. Accurate matching of these markers ensures that the assembly is correct and the fit is maintained.
-
Quality Control: Skilled sewing includes quality control checks throughout the construction to identify and correct any errors that could affect the fit.
