I bet you have a closet full of stuff that you haven't worn in quite a while (or at all!) but you're still holding onto "just because". Maybe it's something nicer than the usual things you wear but you picked it up because it was awesome or on sale and you were determined to find an opportunity to wear it. Maybe it still has the tags on it or maybe you did get a chance to wear it... once... 3 years ago. "But I might still wear it again!"
Be realistic. If it still has tags on it after 6 months then it needs to go. If you bought it specifically for one event and can't think of when you might need it next then it needs to go. Same goes for stuff that doesn't fit, if it's more than one size too big or small then you should get rid of it, trendy seasonal items, shoes that look awesome but pinch (that means they don't fit!), costume jewelry, anything worn out, ripped or stained.
After having a baby I did a massive closet crackdown. Most of my shoes were now too small and I had things I was hanging onto hoping for a chance to wear or I would miraculously shrink into from BEFORE I even got pregnant! I had tiny purses (haha, no way I can fit anything in those!), sparkly scarves and necklaces (babies like to pull on things, ack! choke!) and high heels and mini dresses (I won't be pushing a stroller wearing those!)
