I make sure I wear newer knickers when going out and save the older, more disreputable ones for at home/evenings!Loo brushes with flushable pads, and mops with disposable cloths. Just no!!!!!
I do wish that clothes would spend longer in their prime and not decline so slowly though. It's not that anyone (well not many people) get to see me in my underwear, but some of it really is in a bit of a state. I'd be mortified if I had an accident and it had to be removed, but it still works,so I can't bring myself to throw it out.
