Washing your bra every 2-3 days is a must. Beyond that, bacteria can form under the breasts and near the underarms.
However, as we often tell our customers, it's all about COMMON SENSE.
If you have been exercising or sweating during the day of physical work indoors or outdoors, it should be washed after just one use!
If you are a person who perspires a lot or have larger breast, bacteria will form more quickly under the bust and underarms. So, hop into the wash basket after just one use!
