For best results, you will need to close the bra before washing it so that the hooks do not get caught in the machine or in other fabrics. Next, you can place your bras in a mesh bag, the same one you can use to machine wash your sneakers. Be sure to choose a suitable program so as not to damage your underwear. The American medical center advises “a delicate program” at 30°. When the cycle comes to an end, “lay your bras flat on a towel” and especially avoid putting them in the “dryer, as the heat and vibration will ruin the fit and reduce the stretch properties of your bra.” Like bras, it is better to place panties in a mesh bag and do not exceed 30°C to preserve the elasticity of the materials. It is better to avoid fabric softeners as they can damage the elastics of your lingerie.
