Any time you want a surefire way to look polished and regal, throw on a purple dress. That's exactly what Jamie-Lynn Sigler did at a fashion party in NYC and look what it did for her. However, she could have gone a size down, as the trapeze style tends to make you look wide. The actress toughened the mix by wearing Christian Louboutin's pleated ankle boots (hot) and a macho watch topped with silver bangles. The long silver pendant necklace breaks up the look and gives it a unique flair.
