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. 

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.
