What is the primary function of a lining in garments?

The primary function of a lining in garments is to improve comfort and structure. Lining serves several important purposes in garment construction. It enhances the overall fit of the garment by providing a smooth surface for it to glide on the skin and helps to hide any raw edges, giving a neater finish. Additionally, a lining can add warmth, particularly in outerwear, and can help maintain the shape and drape of the garment, contributing to its durability and comfort when worn.

While linings can indeed add an element of style or aesthetic appeal, their main role is not primarily about decoration. They also do not typically contribute to cost reduction in fabric usage; in fact, adding a lining can increase the cost of the garment due to the additional material and manufacturing processes involved. The idea of providing a design challenge is also not a primary function of a lining; rather, it is more concerned with enhancing the garment's utility and wearability.
