What is the purpose of interlining?

The hard truth behind interlining: Make flabby fabric obey your commands.

1. "Giving fabric bones"—beauties without bones can't stand straight.

Specialized to cure collar cartilage.
Padded shirt collars: Even after working late into the wee hours, the collar tip still sticks out like a razor.
A negative example: Fast fashion brands skimp on interlining, leaving collars ruffled after three washes.
Rescuing flabby fabrics.
Hidden interlining on the front of a coat prevents bulging when buttons are fastened, allowing even chubbier figures to appear thin.

Padding the inside of jeans' plackets keeps a strong man's crotch from collapsing during squats.

Ironing a layer of lining before embroidering a duckling on children's clothing keeps the thread from falling off after a child has pulled at it for three years.

3. Transforming into a temperature barrier—need both style and warmth.

Curtains instantly transform into thermal walls.
Plying single-layer polyester curtains can raise indoor temperatures by 3°C in winter (tested).
A mysterious trick: The lining is one hand wider than the curtain to prevent cold air from entering the folds. Invisible long johns in a suit
