A study has shown that most women only wash their bras every two months. In that, given most people have several bras, they say an individual bras get worn seven times before washing.

So, how often, being honest, would you say you wear one bra before you wash it? I know it's been done before but it's topical today. ?
I only have two bras that fit me. As a heavy 36HH/J, strong bras are hard to come by and very expensive. (At least when I was a 32FF, they were still expensive but could get pretty ones. ?) I would say I wear each one about 4 or 5 times before washing. I take them off as soon as I get home as they are so uncomfortable and I don't wear them on at home days. I wash both every two weeks or so, depending on how often I have been out.
