What is the definition of lining in garment construction?

Lining in garment construction refers to a layer of different material that covers the inside surface of a garment. This layer serves multiple purposes, including improving the garment's comfort, providing a finished look, and enhancing the garment's overall drape. Lining can also help conceal construction details such as seams and interfacings, creating a clean, professional appearance.

When garments are lined, this additional layer can also provide insulation and warmth, particularly in outerwear, while allowing the main fabric to maintain its aesthetic properties. The choice of lining material is important as it should work in harmony with the outer fabric, complementing its texture and weight.
