Slow Food Movement. An international movement begun by Carlo Petrini with a forerunner organisation, Arcigola, founded in 1986 to resist the opening of a McDonald's (fast food restaurant) near the Spanish Steps in Rome.
The slow fashion movement has arisen in opposition to fast fashion, blaming it for pollution (both in the production of clothes and in the decay of synthetic fabrics), shoddy workmanship, and emphasizing very brief trends over classic style.
