The city's Museum of Fashion occupies a suitably fashionable mansion—the 19th-century residence of Marie Brignole-Sale, Duchess of Galliera; and, having emerged from an extensive makeover in September 2013, it is now more stylish than ever. Inside, temporary exhibitions focus on costume and clothing design (a reopening retrospective, for instance, honored the visionary Azzedine Alaïa). Covering key moments in fashion history and showcasing iconic French designers, the museum's collection includes 100,000 dresses and accessories that run the gamut from basic streetwear to haute couture. Details on shows (there are no permanent displays) are available on the museum website. Don't miss the lovely 19th-century garden that encircles the palace.
