PARIS — Sofia Coppola’s “Marie-Antoinette,” which premieres at Cannes today, promises a right royal riot of sartorial excess. Just in time, Paris’ National Union of Museums has put out its own line of objects and accessories fit for a queen.

The collection, inspired by Antoinette’s passions and personal effects, is already on sale in museum shops at the Louvre, the Museum of the History of France, and — of course — Versailles. Some are reproductions of Antoinette’s childhood dresses, silk scarves and china covered in roses. There is also costume jewelry, such as Swarovski’s pearl and crystal version of Antoinette’s infamous diamond necklace. Prices range from $30 for a silk scarf to $250 for a necklace.

Meanwhile, a book based on the diary of the queen’s wardrobe, recorded by Antoinette’s wardrobe keeper, Madame d’Ossun, will be released Oct. 11, in collaboration with the National Archives. The book will feature images of hundreds of swatches from the queen’s dresses, as well as contributions from designers on the influence of Marie-Antoinette’s style today, according to curators Regis Lapasin and Ariane James-Sarazin, the writers of the book. It has not yet been given a title.

The book’s launch will coincide with the opening of a Marie Antoinette-themed exhibition, Oct. 11-18, at the National Archives’ Hotel de Soubise, where certain scenes of Coppola’s movie were shot. For the event, the library will bring out rare archive treasures, such as the diary of King Louis XVI, royal clothing and court documents from Antoinette’s trial. There also will be the final letter penned by the imprisoned queen to her sister, at 4:30 a.m. on Oct. 16, 1793, the day of her execution.
