What does interlining mean?
Interlining is a thin layer inserted between the outer material and the lining of a garment or similar object. Although usually invisible when the item is finished, it can provide support, preserve a garment's shape, add warmth, or improve resistance to wear. In tailoring, the choice and placement of interlining are important because an unsuitable layer may make a garment stiff, bulky, or misshapen. The term is also used commercially for materials intended specifically for this purpose, such as fusible interlining placed inside collars, cuffs, waistbands, and lapels. It is a specialist manufacturing term rather than general vocabulary, but it names a practical and sometimes costly component of high-quality clothing. Related terms such as interline and interliner describe the process and the person or equipment performing it.

- The practice of inserting a thin layer of fabric, foam, or other material between an object's outer covering and its lining in order to reinforce it, provide warmth, or give it structure.
"The coat's interlining gave it a crisp shape without making it feel heavy."
"The tailor replaced the damaged interlining in the jacket."
"A lightweight layer of interlining was used to support the shoulders of the shirt."
The plural is uncommon and is chiefly used when referring to multiple interlining layers, components, or processes.
"Different interlinings can give the same coat a very different feel."
Out of sight but essential, interlining is what keeps many garments looking sharp rather than shapeless.
