If you can't figure out what to wear to your next citizens' advisory committee meeting, might I suggest a Diane von Furstenberg wrap dress? Pair it with a necklace you bought at an outdoor market in South America, and these Cambridge types will eat it UP.
Or more likely, they will not notice your amazing wrap dress or your handcrafted, oversized, Ecuadorean jewelry, as they will be totally focused on a powerpoint presentation about the types of trees the city is considering planting on your street. Whatever. The point is that the DVF is never not appropriate.
