DD asked me how often she should wash her bra and I realised, with horror that I --never-- wash my bras about once a month. I have 3 so that\u0027s about 10 wears per wash. They seem clean - boobs are clean right? \r\n\r\nI washed my maternity bras constantly. \r\n\r\nHow often should a bra be washed?
