I've mentioned before how I have a sort of purgatory for my clothes that I'm not currently loving at the moment. They either get stored in donate bags or in one of the spare closets.
I've heard of mom's who store half of their children's toys at a time and rotate them through every few months. Keeps things fresh and exciting. I think sometimes clothes are like that too. Some things I buy and wear, wear, wear and then they get a little tired. If I hide them for several months before deciding what to do with them, it gives me the opportunity to get excited about them again before banishing them forever.
Many times I find that I love something more the "second time around" than when I initially got it.
