Realising that your closet isn't sustainable can be an unsettling and overwhelming thought. So when organising and disposing, MacPhee recommends "not feeling guilty or pressure to do everything at once." Any little step is a step in the right direction. It's important to go back to your definition of sustainability and decide what's important for you and how to make those changes.
When looking at your closet, try to figure out the difference in the clothes that have lasted a long time and the ones that easily rip and spoil. "Unfortunately, because of the H&M and Forever 21 culture, we are so far removed from what quality is," DiSalvo explains when discussing how quality is wrongly associated with price. She recommends going, "into your closet and looking at the items that have lasted long. Pull it apart, look at the seams, look at the fabric: touch it, feel it, pull it." Once you've done that, compare it to the items that are breaking, and train yourself to see and feel quality.
When disposing of garments, make sure you are donating to reputable places. And if you are struggling to give up items that are no longer of use, MacPhee encourages writing a note on the clothing you plan to give away. "Write a little note on the back of the label to remind yourself and the future wearer that wherever [the clothing item] goes, it's like a piece of you just went forward."
