When you hang your clothes in the closet, hang them according to seasons:
summer (short sleeves and tank tops) and winter (long sleeves and sweaters). It is easier to find the clothing you need when it is separated by seasons.
Hang your clothes according to color. Then you will be able to see the quantity of red, blue, green blouses that you own.
Having your clothes in color order will allow you more efficiency in picking your clothing when you are getting dressed.
Turn all your clothes hangers on the back side of the rail and then when you wear it, wash it and return it to the hanger, put it on the front side of the rail.
At the end of the season, all the clothes still hung on the back side of the rail will be clothing you haven't worn all season and can be edited out ofyour closet.
