Mr JK and I are a bit lackadaisical about clothes. When we're on our own, obviously. Or in front of the children. They're 3 and 5 and currently don't seem bothered.
My mother wasa bit half-hearted about clothes, though not always in terms of being nekkid - she used to take her bra off down one sleeve as soon as she got in form work, sometimes stuffing it under a cushion on the sofa to be discovered by some hapless individual much, much later. And on her first trip to the loo her knickers came off too (I'm the same thinking about it).
It's not that I can't stand clothes, or seek to make a point, it's a matter of convenience and laziness and in the case of bras, comfort.
