Looslining

Looslining is a term found in limited technical and craft literature, and it lacks a universally accepted definition. The word combines "loose" and "lining," and practitioners use it to describe a lining that is purposefully not tightly affixed to a substrate, or designed to fit loosely within a shell. Exact meanings vary by field.

In textile and fashion contexts, looslining may denote a lining constructed or installed with extra ease to promote drape, ventilation, or adaptability to seasonal changes. It may involve a lining that is cut slightly smaller than the outer fabric so there is no firm seam along the edges, or a removable or partially attached lining used for modular garments. In upholstery or automotive interiors, "looslining" has been used to refer to a loose inner layer behind a face fabric to allow compression or sound dampening.

The term is uncommon and largely appears in niche manuals, historical descriptions, or descriptive glossaries. Because of the lack of standard usage, readers should consult discipline-specific sources to determine whether looslining refers to a loose fit, a removable lining, or another practice in that context. Related terms include loose lining, loose-fit lining, and removable lining.
