The term 'Dandy Accessory' refers to two different types of neckwear: a CRAVAT and an ASCOT. A CRAVAT is a type of necktie that originated in the 17th century and is typically made from silk or other fine fabrics. An ASCOT is a more formal type of neckwear, usually made from silk or satin, and is tied in a bow-like knot. Both cravats and ascots are considered fashionable accessories for men and can be worn with suits or other formal attire.
