The traje de luces (suit of lights) is the traditional clothing that Spanish bullfighters (matadors, toreros, picadors and rejoneadors) wear in the bullring. The term originates from the sequins and reflective threads of gold or silver. These trajes are based on the flamboyant costumes of the 18th-century dandies and showmen involved in tauromachia, which later became exclusive to the bullfighting ritual. Later adornments include the montera hat, elaborate embroidery and decorative accessories.

Getting dressed to kill constitutes a ceremonious ritual by itself, the matador is attended by a squire (mozo de espadas) who helps him to get dressed, often according to a "lucky" ritual in the privacy of a hotel room.
