A shrug is a cropped, cardigan-like garment with short or long sleeves cut in one with the body, typically knitted. Generally, a shrug covers less of the body than a vest would, but it is more tailored than a shawl. Shrugs are typically worn as the outermost layer of an outfit, with a full shirt, tank top, or dress beneath.
A bolero jacket or bolero (pronounced // or // in British English and // in American English) is a more formal garment of similar construction but made of stiffer fabric, essentially a short tailored jacket, inspired by the matador's chaquetilla. Like the shrug, the sides of the bolero only meet at one point.
