Channeling Betty Draper, Moynahan unwinds in a full-skirted cornflower blue wool and chiffon dress with a crinoline lining that gives it extra oomph. Demure, sure, but the style has been updated with modern details, like an exposed seam down the back. "It's nice that long skirts are popular again, because they're very wearable," says Moynahan.
