What is the primary purpose of interfacing in garment construction?

The primary purpose of interfacing in garment construction is to add structure. Interfacing is a material that is placed between the fashion fabric and the lining or facing to support and stabilize areas such as collars, cuffs, button plackets, and waistbands. By doing this, interfacing enhances the garment's overall shape and durability. This support allows the fabric to maintain its form, ensuring that the finished garment looks sharp and well-constructed.

Adding color, providing warmth, and creating texture, while they may be features of other fabric treatments or design elements, are not the main functions of interfacing. Color is generally applied through fabric choice or dyeing processes, warmth is usually addressed by the weight and type of fabric chosen, and texture is created through techniques like weaving or adding embellishments. Interfacing specifically targets structure and stability in garments, which is crucial for achieving a professional finish.
