State on the brief whether the trousers are lined at the front to the knee or left unlined, and the lining colour, because it changes how the trouser slides on, how it feels against the leg and how the cloth wears at the knee — and it is fixed when the sample is sealed. The ApparelX glossary describes a knee lining as a partial lining on the inside of the front panels, from around the waist to around the knee, used to ease putting the trousers on, add comfort against the skin and reduce wear on the outer cloth; it also advises stating the placement and length in the spec.

Which trouser lining details go on the brief?
- Lining: Front to the knee, or unlined — One choice per style (bulk) or per client (MTM)
- Length: Where the lining stops, stated on the spec — So both sides mean the same thing
- Colour: Match the cloth, or match the jacket lining — Shows when the trouser is turned
- Stretch cloth: Check the lining moves with the cloth at the knee — Otherwise the knee feels tight
When is unlined the better brief?
- Light summer cloths such as linen or cotton are often left unlined to stay cooler.
- Wool and brushed cloths that cling to the leg are where a knee lining is most often briefed.
- Whichever you choose, the sealed sample shows it, and QC checks bulk against it.
Where does this sit on the clock?
Trouser lining is part of construction, so it belongs in the lock: sample 7–14 days starts when measurements, cloth and construction are locked, and production 14–21 days follows sample approval. A change after the seal needs written confirmation. Production days are not delivery days.
