It was a Dolce & Gabbana kind of weekend in the Hamptons when Stefano and Domenico invited well-dressed guests to get intimate with the label's Winter collection. Lauren Santo Domingo, Julie Macklowe, and Samantha Boardman Rosen were among the garden party attendees who lunched in Southampton with the fresh-off-the-runway designs. In Laguna Beach the mood was equally festive, where attendees of the annual Oceana SeaChange Summer party enjoyed the great outdoors.
Later in the week, Anna Wintour joined Roger Federer for Moët & Chandon's Chelsea Piers anniversary bash, and New York's hottest club with a rooftop pool celebrated its 10th anniversary — with the help of a very chic set, of course. Get a look at all the stylish parties attended, here in the gallery.
