Input: Question: Which town where Missoni did work or showed their work was the largest? Passage:The business was founded in 1953, when Ottavio and Rosita Missoni set up a small knitwear workshop in Gallarate, Italy. They presented their first collection under the Missoni label in Milan in 1958. The business prospered, with the support of fashion editor Anna Piaggi, then at Arianna magazine. Rosita met the French stylist Emmanuelle Khanh in New York in 1965, which led to a collaboration and a new collection the following year. In April 1967, they were invited to show at the Pitti Palace in Florence. Rosita told the models to remove their bras, supposedly because they were the wrong color, and showed through the thin lamé blouses. The material became transparent under the lights and caused a sensation. The Missonis were not invited back the following year, but the business grew; a new factory in Sumirago was built in 1969. Missoni designs were championed in the USA by Diana Vreeland, editor of American Vogue, and a Missoni boutique was opened in Bloomingdales.
