Avoid fabric softener: It can clog fibers and irritate the skin.
Dry your underwear thoroughly: Air drying better preserves fabrics.
When should you replace your underwear?

Even when properly cared for, underwear doesn’t last forever. On average, it’s recommended to replace it every 6 to 12 months, but there are some signs that should alert you sooner:

Signs it’s time to change them:

Loose elastics: If they no longer hold well, they have lost their support.
Damaged or holed fabric: Frayed or rough fabric can cause irritation.
Poor absorption: If they no longer regulate moisture well, they become uncomfortable.
Lingering odors: If the odor remains after washing, the fibers are saturated with bacteria and perspiration residue.
