What to keep, what to purge?

The age old dilemma: what should I get rid of in my closet? I have a close friend that has a logical answer:
buy one, purge two. Logical to her, impossible for me. I am a bit of a hoarder (I really hate to admit that, but it's true), I love my 80's and 90's wardrobe. I fondly remember it to myself as my "back in the day" wardrobe. I keep thinking that these fabulous items (if kept long enough) will come back into style. Which, I have to say a lot of them do - just renamed and redesigned. Belts? What about the peplum belts? The wide leather ones with oversized buckles? The yellow gold ones that stretched? Why are these not at the top of the fashion pages? Ahhh, their day will come.
And don't forget the faux animal print leggings (better known as leggins' to my east coast family and friends).  Honestly, does turquoise or hot pink leopard ever go out of style? Certainly not my leopard - fringed bolero jacket, that was my fave back then.
I guess the reason I hesitate to purge the many "questionable gems" in my closet is that the task is truly overwhelming.

I need to make a plan of attack, here is a fool proof plan:

1. try it on (with hair and makeup) in front of a full length mirror
2. does it fit properly?
3. does it look good on me?
4. is this outfit representing the real me?
5. big question: will I ever wear it?

Once I go through this process, I should be able to have a  big pile of funk and a nice tidy closet to be proud of.  Give this a try and let me know how successful you are.
I will keep you posted on my progress.  Happy purging!
