Nicki scarves were initially used by artisans and farm workers in the Netherlands and Great Britain. With the beginning of industrialization in the 19th century, industrial workers also carried them. In various versions, they became modern several times in the 20th century, especially around 1950 and 1970. At the beginning of 2002, designer Gabriele Strehle made yellow Nicki scarves part of the uniform of Lufthansa stewardesses.
