Washing lingerie in the washing machine
Washing your bras with an automatic program can cause them to lose their shape or stretch too much. Try washing your bras, lace lingerie, nylon tights, and swimsuits by hand. If finding the time to do proves impossible, wash them in the machine using a gentle program and a water temperature of 90°F. You can also put them in a washing bag or pillowcase to make sure they will not be damaged.
