In clothing and similar applications, a gore is a triangular or trapezoidal piece of a textile as might be used in shaping a garment to fit contours of the body.

The word is derived from Old English gār, meaning spear. In the course of time the word came to be used for a piece of cloth used in making clothes.^[1] In dressmaking and hatmaking, it refers to triangular or rhomboid pieces of fabric which are combined to create a fuller three dimensional effect. In knitting gloves and mittens, a "thumb gore" is often incorporated from the wrist part way to the tip of the thumb to accommodate the gradually increasing width of the hand.
