The socks make the outfit! This pair features an homage to Vincent van Gogh's Portrait of Postman Roulin.
In February 1888 Van Gogh moved to Arles, in the south of France, and continued to paint landscapes and portraits. Between late July 1888 and April 1889, he painted at least six portraits of Joseph-Etienne Roulin (1841–1903), a postman in Arles.
One size fits most.
