I will choose a day which I dedicated to run through every clothes in the closet. Usually,​ I will do this every three months.

1. Throw any clothes that I didn't wear or wear once for the past three months.
2. I arrange my clothes based on the purpose of wearing the clothes.
3. I avoid buying more clothes to keep the closet neat.
4. Hang every clothes and make sure you can see them all once you open the closet.

Hope these tips help you :)
