Hand wash in cool water with a gentle detergent made for delicates. Avoid fabric softener—it can coat fibres and reduce elasticity. Rinse well and squeeze (don’t wring) before laying flat to dry. If you machine wash, use a mesh bag and a delicate cycle; cold water only.

Store bras with cups nested or flat so they keep their shape. Avoid crushing under heavy items. Knickers can be folded or stacked; keep them in a drawer or bag that breathes so moisture doesn’t sit.

With good care, bras and knickers can last well. Elastic and fabric fatigue over time; rotation (not wearing the same piece every day) helps. Replace when fit or comfort is compromised—not on a fixed schedule.

Bras: Band fails on the tightest hook; underwire damage or poke; elastic recovery loss (band or straps no longer snap back). When support or comfort is gone, it’s time.

Knickers: Elastic recovery loss; fabric thinning that affects comfort or opacity. Replace when pilling affects comfort, not just appearance.
