There are many ways to organize the garments in your closet. My favorite is to group similar items together.
For today’s task, go through your closet and group your tops by sleeve-length so sleeveless tops are together, progressing to long-sleeved tops and layers.
If it works for your wardrobe, you may want to further organize these groups by color or where you wear the tops (work, casual, party) so it will be easier to find what you want. If you encounter items you don’t, won’t, or can’t wear, pop them into your “to donate” box.
