I always keep out one or two warm garments in case of unseasonably cold weather or an unexpected trip to a cold climate. After unpacking your spring things you'll want to air them out. Hang them outdoors to imbue them with true spring freshness. It's also a good idea to edit these too. Get rid of anything that doesn't fit anymore or is out of style.
Spring is almost here, so remember, an ounce of preparation is worth a pound of panic.
