A vest pattern is a set of instructions and diagrams to construct a vest, which is a sleeveless garment that covers the torso and typically fastens in the front. Vest patterns are typically designed for fabric and leather material, but the patterns can also be knitted or crocheted.
Vest patterns include formal and informal styles. A man's tailored, three-piece suit includes a formal vest in a coordinating or matching fabric. Informal vest style are more common and go with casual clothes, such as jeans. Vest patterns can be for lined or unlined garments, or even outerwear. Some outerwear vests are made from sheepskin or synthetic fabrics that are filled with down or polyester for warmth. Safety vests are embellished with bright, reflective fabrics and help improve visibility for construction workers and bicyclists.
