Often, clients ask me whether or not to switch their clothes around in their closets depending on the season. Should you move your winter clothes to the guest closet in the summer? Should you pack up your swimsuits and tank tops all winter long?
The answer depends more on your space than on your preference. How big is your closet? Can it fit all of your clothes from every season? If you have a smaller closet, then you your needs are different than someone with a large walk in closet.
If your closet size determines that you should pack up seasonal clothes, then pick a date that works for you every year, and make that the day you switch out clothes. Spring and Fall equinox? May 1st and November 1st? I suggest keeping your clothes on the hanger and carrying them to another unused closet or laying them flat in an underbed storage box on the hanger, so they stay unwrinkled and easy to move around. Only pack up the clothes you are positive you will not need for the next few months. Jackets, short sleeve shirts, shorts. Otherwise, you will constantly be looking for the missing pieces.
If you have enough room in your closet to store all of your clothes, then don't waste time moving things around. Organize all the clothes in order from sleeveless, short sleeve, long sleeves, and you will still easily find which section you need depending on the season. Keep jackets and scarves together in an area that you don't need to access as much, and keep swimsuits and beach coverups together in a drawer or basket.
