Start creating categories and labels for each category. I recommend these 3: Keep, Donate, Recycle.
While this step is optional, I tend to prefer to keep my closet in color order to make it easier to find items.
Take any items that may have stains or rips put them aside to go to the dry cleaners for cleaning and tailoring.
The last step is to hang all the remaining clothes back in your closet and get ready to enjoy your new Spring ready closet!
