The London West Hollywood rooftop was transformed into the ultimate fashion destination when designer Yigal Azrouel showed his Spring '12 collection in LA last night. Celeb admirers like Lauren Conrad and Nicole Richie popped by to check out the pieces and to do some postpartying at the hotel's gorgeous rooftop lounge. I caught up with Yigal after the show and he told me why LA women will love his Spring line: "Part of my inspiration was Hollywood chic, the laid-back kind of women, effortless," he said. "I love the simplicity and architecture. It can be a dress you can wear to the beach." Step inside for some fun snaps from last night's affair and to hear which LA 'hood Yigal loves to chill at when he's in town.
