I think some of the posts have crossed the line between general pondering on what can make you look older, and being a bit sneery towards the way some older people dress.
I think that too and if you throw the smugness into the mix....
Sometimes people look they way they are, due to illness or disability.
You would accuse me of slouching, if you saw me, because I have spinal fractures and a curved back. In addition, despite three monthly visits to the dentist, my teeth are not in a good state, for a number of medical reasons. Bad teeth are not always due to neglect and lack of personal care.
Thank goodness, I haven't taken some of the judgemental comments personally.
However, I do stand by my comment about, baggy, saggy bottomed, too short trousers. That can be easily rectified
