gusset

GUSS-it /ˈɡʌsɪt/
nounC1
technicalfashion

A triangular or diamond-shaped piece of fabric inserted into a seam to add breadth, reduce stress, and allow freedom of movement.

In undergarments (especially panties and tights), the gusset is the breathable, often cotton-lined panel in the crotch area designed for hygiene and comfort.

The story behind the word. The word originally referred to a piece of flexible chainmail or plate armor designed to protect a knight's vulnerable armpits. Because the armpit required maximum mobility, this protective insert had to be specially shaped—a design principle that tailors later adopted for civilian clothing.
