When do you call it quits? If the tee has permanent stains, holes in the middle, or the fabric has lost its shape, it's time to retire it. In Florida's humidity, you'll also notice that once a tee starts to smell even after washing, that's a sign the fibers have broken down.

Retiring doesn't mean you have to throw it away. Repurpose it as a cleaning rag or donate it if it's still wearable. But for your wardrobe, let it go. Holding on to a tee that's past its prime just adds clutter to your drawer.
