Clothing is always the first category because you begin and end your day in your clothing. Not only that, and more importantly, you wear them closest to your heart and listening to your heart is the first step in developing your spark-joy senses.
Gathering all clothing into one spot and placing it on top of your bed allows you to fully see how much you own. Holding each item in your hands and assessing each one individually for joy will effectively guide you as to what stays and what will be discarded.
Finding out what sparks joy for you by choosing your top 3 favorite items and then comparing them to something you know is going to be discarded will keep you on track with moving through the clothing category effectively and efficiently.
**Tidy Tip: Everything you keep should feel like your top 3 favorite items.**
Once you have chosen all of your spark joy items, folding the pieces that go into drawers or bins so that they stand up vertically will make it easy to always see what you have and nothing will be lost or forgotten.
