Spring Cleaning: Closet Edition

Now that I've moved back home and all my boxes from school have arrived, I'm going through a major organization and purge, especially of my closet. My closet and other clothing storage space (pictured above and below) are fairly limited. That said, I have more than enough space for a full wardrobe. The problem is, I have way more clothes than what one would call a full wardrobe. So it's time for a little spring cleaning and purging.

Here's my space:

So what am I going to do with it? My goal is to remove the smaller drawer unit in the closet to free up some space for hanging clothes (the bottoms of my dresses tend to get smushed against the top of that unit). I'm also hoping to free up some space on the top shelf so that I can store out-of-season clothes (like my bajillion fall/winter sweaters) up there. And I'm replacing my plastic hangers too and replacing them with the slim velvety huggable hangers I had at school - I could definitely use the extra space they provide me. Of course to do this I'm going to need to take a hard line with my clothes - time to get real about what I really will or won't wear. I'm not going through this alone though - I've got tips from Lucky's amazing closet organization guide and Real Simple's checklist, plus my mother is more than willing to encourage me (especially when I'm getting rid of stuff). Have you ever received any great closet organization advice?
