1) It's a good idea to have 3 bras that you rotate - think one on your body, one in your drawer and one in the wash. This will extend the life of your bras.
2) Hand wash if you can - Wash by hand using cold water and a mild detergent, both of which are more gentle on fabric and help to retain elasticity.
3) Machine wash if you must - We know that not everyone has the time to wash their bras by hand. If you do put your bras in the washing machine, use cold water, the gentlest cycle and place the items in a lingerie bag. Always fasten hooks so that they don’t get caught on anything else.
4) Lay flat to dry - Heat from dryers will wear them out much more quickly, and can warp the elastic. Instead, lay your bras flat (or hang them) to dry.
