The recent spate of amazing days — 70 degrees and sunny, whaaat? — has us feeling pretty confident that spring is here to stay. And we couldn't be more excited about it, because it means we can officially change over our closets, pack away the bundling gear, and start concocting some fresh new outfits.However, in true D.C. fashion, we're still going to have the odd blustery morning or chilly evening, so you can't put a complete stop to layering just yet. We've already hooked you up with our favorite jackets for the season, and now, we're going to help you stock up on another spring staple: the cardigan.
