Other Details: A hip crowd of stylists and L.A.'s fashion set gathered at Chateau Marmont for a summer soiree in honor of the Fall 2011 collection for Simone. The line's designer Katie Nehra was on hand to work with guests to design their own custom leather jackets in between air-kisses and sipping cocktails at the iconic hotel. While most of us still need to catch up on getting our summer wardrobe essentials, attendees of last night's cocktail party were also able to get a head-start on putting their most fashionable foot forward into next season with the Simone Fall collection available for pre-order.  [Katie Nehra photo via]

Sure, it's a children's novel about dancing but she still had to be literate to pen it, right? With the help of a very pregnant Jessica Alba and husband Cash Warren, last night Relota celebrated the launch of her publication at Dragon Books where guests were invited to bring their kids along and have balloon animals made special just for them.
