I'm in love with these ones with the flip open tops from Crate & Barrel. I have to say that clear is the way to go on these storage containers -- otherwise I would have to check every single one before I found what I was looking for. (Maybe a label maker would come in handy too???)
Another way that we stay super organized is by having drawer organizers for our drawers with little items of clothing. Here are the ones I have from The Container Store (can I say how much I L-O-V-E that place?!?!)
I also really love these more elegant looking ones from The Container Store too (and HEY, they're brown and blue!!):
Another thing I'm TOTALLY in love with are hooks -- yes, hooks. I can't think of a better way to avoid clothes left on the floor. I keep anything I might wear again (such as working/project clothes) on a hook in the bathroom. It's the best thing, in my opinion.

As for closet accessories I'm a huge fan of a belt hanger (also good for scarves!). This one is from The Container Store too.
Our closet will definitely be redone in the future. It's not high on our priority list as we have other closets we can use in the meanwhile. But someday I will be cleaning it up and making room for all my hanging things. Right now Kevin hogs the whole darn thing! Just kidding -- it's a good arrangement for now as he definitely has more hanging clothes than I do.
A picture of my dream closet? Heeere you go:
Do you recognize it? It's the closet that Big makes for Carrie in Sex and the City. Sadly I think we'd have to take over two bedrooms in our house for a closet like that. But oh, to dream!
So our future closet redo won't be quite like this, but definitely organized.
