Spring in Washington. Although long-awaited, it's also notoriously short-lived. You know what we're talking about — you get a few good wears out of that darling trench before you wake up to a blast of heat and suffocating humidity. Be that as it may, a spring jacket is still an essential piece for a well-stocked mid-Atlantic wardrobe. We get enough chilly mornings and breezy nights to guarantee you'll get plenty of use out of a lightweight topper, and it's ideal for days when your office is less than temperate. Plus, when the mercury takes a sudden dip, a structured jacket is the ideal layer to balance a cozy sweater. So, we've gathered up a batch of our favorite options that you can wear now and later.
