Do you switch out clothes in your closet when the seasons change, or do you have only one closet where you store everything for all seasons?

I have only one closet, but it is getting pretty full. It is getting to be a pain to get stuff in and out. I am wondering about taking out my heavier winter stuff once spring is here to stay, but I'm not quite sure where to go with it.

If you do take stuff out of your closet as the seasons change, how do you store it?
