It could have been the San Francisco Sex and the City premiere party. Last Saturday night, over 1,000 people were turned away at the door, while 3,000 made it in, decked out in decidedly more flashy outfits than typical for the fleece-and-crocs locale. It was the grand opening of the new Contemporary Jewish Museum in San Francisco, and a celebration of the holiday Shavuot rolled into an all-night cultural arts festival called DAWN. The $47.5 million building (designed by Daniel Libeskind as an addition to a brick, circa-1907 power company substation) opens onto a new public plaza across the street from the Yerba Buena Gardens, just a block away from the SF Musem of Modern Art.

When we aren't waiting with breath that is bated for updates to Lindsay "Ronson" Lohan's probably fake Facebook profile, we sometimes like to gawk at art. On display to the public, starting today, is "Jeff Koons on the Roof" at the Met. Featuring three large-scale installations—most notable among them, Balloon Dog (Yellow), pictured left—the 10,000 square-foot rooftop space is the perfect place to showcase playful works by the iconic American artist. Koons's work will be on display until mid-October (LiLo's wall probably won't be).

In Paris, the answer to every civic problem might actually be: more fashion! Indeed, anchoring the Docks de Paris project revival of a downtrodden Left Bank industrial site along the quai D'Austerlitz, La Cite de la Mode et du Design is set to be the capital's fourth museum dedicated to matters sartorial. As the name indicates, this one will also address a broader spectrum of design, and up the fab factor by incorporating designer boutiques and a chic rooftop restaurant from the people behind Georges, the Pompidou's futuristic eatery in the sky.

Whether or not Interpol’s Carlos D and/or The Horrors can claim all the credit, it’s certainly hip to be Goth again. So it’s fitting that the world’s most fashionable city pay homage to history’s most enduringly sexy beast. Jacques Sirgent, France’s premier practitioner of Dracophilia, has now opened Musée des Vampires, his vampiric stash to all the macabre-hearted and Kohl-painted amongst the living. His salaciously creepy collection ranges from film posters to costumes and weapons; and private tours might include parlour games, discussions (no doubt many regarding the virtues of the new Bauhaus record), and even dinner parties—though you might want to scrutinize le vin rouge before imbibing.
