Keep it or bin it

I'm so looking forward to clearing out my dresser. So many things I never wear anymore, because it no longer fits or because it's dated. I'm normally not puzzled to figure out which things I want to keep or bin. But this time, I have no idea. I shouldn't bin all of the clothes that are too small or outdated. I might need them somewhere soon. I can't keep buying new clothes all the time. There are too many different sizes in my wardrobe already.
As soon as my back is better, I want to give it a try. I'll let you know the outcome.
