Translation: Basic but not boring

A dress or skirt isn't necessary for at-home get-togethers, but khakis don't quite cut it either. Elizabeth Rogers, an environmental consultant and author of Shift Your Habit: Easy Ways to Save Money, Simplify Your Life, and Save the Planet, stands out in a plaid blazer (Libertine), leather pants (Current Elliott), and platforms (Brian Atwood). "Each winter I update with a great jacket," says Rogers, whose book advises readers on how to have more for less. "The crystal elbow patches make this one modern."
