In the last few months I've noticed DM wearing the same blouse for several days (often over a week) with food spills on. I took her to the GP a couple of months ago, and her trousers and top were both visibly grubby - she was then hospitalised and I was able to pop them in the wash. I just don't how to kindly point out to someone their clothes are grubby, and they should wash them more often. DH mentioned it to me, after she was with us for Christmas Day, so it's not just me being fussy.
