Always wash your bras by hand
Washing machines can cause snags, rips, and tears. We recommend that you wash your bras, by hand, after every second or third wear with a soap designed for delicate fabrics.
Let them air dry
The high-heat and tumbling action of dryers can ruin elastic and cups. Alway lay your bras flat or hang them to dry. They'll thank you for it.
Give them a break!
Literally, give your bra a break after you wear it.
Try to alternate the bras in your wardrobe; don't wear the same bra 2 days in a row. If you give the band 24 hours to rest after being stretched, it can help to double the life of your bra, keeping your band firmer longer.
