In the balmy summer night, an international set of beautiful people ascended to the roof of the Standard Hotel to celebrate Ferragamo's new fragrance, Attimo ("moment" in Italian).

The glamorous crowd was like the perfect casting for the kind of cool girl Attimo is meant to attract. Hanging above the pool (tile floor inscribed with the logo) of nightclub Le Bain, and on the grass covered roof, the thrall included Vladimir Restoin, sisters Victoria and Vanessa Traina, hostess Fabiola Beracasa, a buzz-cut Agyness Dean, actors Sebastian Stan and Allison Pill, and artists Max Snow, and Dustin Yellin.

Dree Hemmingway, who looked stunning in a long slinky metallic Ferragamo dress with a bra showing underneath, is the face of the fragrance. Lensman, Craig McDean, also in attendance with wife Tabitha Simmons, shot the platinum blond for the campaign.

"It seems like everyone is really living in the Attimo- the moment- right now and having a great time," Giovanna Ferragamo told StyleList. "I havent been to one of these in a while." Jewelry designer, Genevieve Jones, also wearing a Ferragamo long dress (the new short!) concurred. "This is splendid!"

After midnight, the group traipsed across the gold flecked carpet to the Boom Boom Room, and the dance party really got started. With the drinks flowing, it became even more of a "moment" to remember.

Speaking of drinks, here's a way to get through a night without a hangover!
