NEW YORK — If it’s an Italian zigzag or stripe — in a rainbow of colors, of course — it’s a good bet it’s Missoni. In 50 years, the Missoni family — parents Ottavio and Rosita and their children, Angela, Vittorio and Luca — have built a fashion empire on a simple design ethos: Bold is better. The house’s classic kaleidoscope knits made a splash on the runways during the Seventies and Eighties and soon became the favorite of fashion-loving jet-setters everywhere. Once again, under the watchful eye of Angela, who took over design duties with the spring 1998 collection, the house is a major player on the runways. And those glittering patterns and prints? A staple at society parties and on the red carpet. Here, WWD takes a look at Missoni, the family and the fashion, through the years.
