Cat Deeley donned a sexy one-shoulder dress to a very fashionable dinner that included Rachel Zoe, Sofia Vergara, and other notable women in TV. Cat's purple frock has a California ease about it, and she added some glamour with a Jimmy Choo leopard-print clutch ($51). Fab tip: add a cream blazer ($238) for an extra dose of warmth and sophistication. Click my picks to get this cocktail-ready outfit now.
