One of my favorite easy closet organizing tips for the new year or the beginning of any season is to just rotate the hangers of everything in the closet to face the other way. As you wear and put away clothes you just put the hangers back the way you normally would.
It’s a little weird at first but it lets you visually see what you wear and don’t wear.
At the end of season or year if you get that far. The clothes on the hangers are the first things you should grab for the donation bag, no questions asked. If it’s sentimental take a photo – you can even hang the photo in your closet but get rid of the unworn clothes and make more space and room for the clothes you wear.
You will be surprised how much more you wear with a less crowded closet.
