The lavallière is a type of cravat similar to the bow tie that was popularly worn in the 19th century in France.

The name is associated with the Duchess of La Vallière (mistress of Louis XIV).^[2] It was primarily worn by women, artists, students, and intellectuals associated with the political left in 19th century France.
