Smart in all its many forms is the key concept for the luxury class in September. Of course it’s back-to-school season for most of the world, and the time when many top authors release their latest works. In the world of culture, we’re meant to return to serious fare: cerebral and provocative films, plays and musical performances abound. But it’s not all about being book-smart. It’s also about being chic-smart: September brings Fashion Weeks in New York, London, Milan and Paris; design fairs in several major cities; auctions of fabulous clothes and jewels; and museum exhibits about iconic fashion houses and designers. In addition, the entertainment world will be ablaze with award shows, premieres and film festivals (accompanied by de rigueur red carpet looks, natch). The coming of the fall harvest is the catalyst for glorious food and wine festivals. Plus there’ll be football, yacht shows, auto shows and F1 Grand Prix racing. Eat, drink, read and be merry: here’s our Dandelion Chandelier list of the most important events in the luxury ecosystem this month.
