Lining fabric is a layer of material used to cover the inside of garments and other sewn items. It serves both practical and aesthetic purposes, including:   

Enhancing comfort: Linings can make garments easier to put on and take off, especially those made from less elastic materials like wool or leather. They also prevent the outer fabric from clinging to the body, improving overall comfort.   

Protecting the outer fabric: Linings act as a barrier, shielding the outer fabric from damage, abrasion, and dirt. This helps the garment maintain its appearance for longer.   

Improving fit and aesthetics: Linings help garments maintain their shape and prevent the outer fabric from wrinkling or deforming. This contributes to a more polished and elegant look.   

Adding warmth: In winter garments, linings can provide an extra layer of insulation, making the garment warmer and more comfortable.   

Lining fabrics come in various materials, each with its own properties:   

Polyester: Durable, affordable, and wrinkle-resistant.   
Silk: Luxurious, lightweight, and breathable, but more delicate and expensive.   
Viscose: Soft, drapes well, and is more breathable than polyester.   
Cotton: Natural, breathable, and comfortable, but can be less durable than other options.

The choice of lining fabric depends on the specific garment, desired properties, and budget.
