The Event: The Mad Men season seven back half screening at the Museum of Modern Art in New York City on Sunday, where the actress was joined by co-stars January Jones (in Preen), Elisabeth Moss (in J. Mendel), Jon Hamm and John Slattery, as well as creator Matthew Weiner.

Why We Dig: If there's anyone who knows how to work her curves, it's Christina Hendricks. The actress stood out in her latest red-carpet get-up by her go-to designer — a full-length frock that hugged her figure in all the right places. To let her shimmery dress do the talking, the actress kept her lightened locks in a loose wave. Sexy and sassy, just the way Joan Holloway would have preferred.
