unlined

Unlined is an adjective describing an object that lacks a lining, or an interior layer of fabric, padding, or material. In textiles and apparel, an unlined garment has no separate lining fabric; the outer fabric forms the interior surface. The term is commonly contrasted with lined, half-lined, or fully lined items. In window treatments and upholstery, unlined refers to products without a lining or backing material, resulting in a lighter, more translucent result.

In clothing, unlined garments are typically lighter and cooler and often rely on the finish of the outer fabric or on simple seams and hems for construction. They are common in summer clothing, dresses, and some types of outerwear where a soft, fluid drape is desired. Leather and suede pieces are frequently sold unlined, which preserves the texture and reduces weight, but can make the interior less smooth and the item more prone to catching on underlayers.

In curtains and drapery, unlined options lack a backing, making them more affordable and allowing more light to pass through, but offering less insulation and privacy compared with lined versions. In upholstery and tailoring, an unlined approach can produce a more casual or natural look, but may require careful finishing of raw edges and seam allowances to prevent fraying.

Care and maintenance for unlined items depend on the outer material and construction. They may require gentler handling, shorter life in high-friction areas, and attention to seam integrity, since there is no additional interior layer to conceal or protect edges.
