Empty all of the pockets. Throughout the cold winter months, you may have shoved items into them. Gloves, hats, important notes and even money could be lurking in there. Go through all of the pockets to ensure that nothing important is left behind.
Inspect your coats carefully to find any imperfections. This could be anything from a loose button to a stain. Make notes of what you would like to fix or even alter on the coats. Creating a list will help you remember everything that you need to do. Complete these tasks before next winter.
Clean your coats. Have them professionally cleaned or wash them yourself, but follow the instructions on the coats' care tags. Many heavy winter coats must be dry cleaned. There can be an added bonus to this, though, as most dry cleaners will also take care of little things such as loose buttons, frays or other wear and tear.
Store your winter coats in an airtight container until the cold weather returns. In doing so, you are getting them out of the way. These containers will also keep moths, spiders and other pests from getting to your coats and damaging them.
Consider whether you need or want a new winter coat before next winter. If so, hit the end-of-season clearance sales to score a nice, new winter coat at a bargain price.
