take out everything that does not fit, that has a stain or rip and give it away to charity, then go back in and get rid of anything you have not worn in the last three years.
Look through what is left, if you live in climate with seasonal clothing, pull out the winter to box away for next winter. sort what is left into outfits to hang together, if you have tops with no bottoms or vice versa, get rid of them
check each outfit to make sure you have shoes that go with
pitch the shoes that don't go with anything
I do this 2x a year and it makes life much easier, I also hang things in order of how I wear them so I am not wearing the same thing over and over - I grab an outfit from the left side of my closet and then hang clean stuff at the end of the line on the right. If I take a pass on an outfit repeatedly ( cause of weather or bloating) or they are my glitter jeans from contempo and we are going to Church
or can't make myself wear it after all, I try to mix match again I try to shop about four times a year and I also get rid of special occasion items after wearing them a couple times cause I like to have something new.
