Help, I can’t find the only trousers mum will wear

[greenbeansnspinach]

Thanks people for helpful replies about security for mum, a few threads ago!
Another query here. Mum will only wear one pair of trousers, which she bought in a charity shop years ago. They are Damart, the essential characteristic being they don’t have a wide or bulky waistband. I will try to attach a photo, taken on the only occasion I’ve managed to get them off her for washing.
i have brought so many trousers to her that I’ve lost count, and all have been rejected. Damart don’t seem to do these any more.
Mum is under 5ft now, slight build and not overweight but her tummy muscles have gone. Used to have an hourglass figure so still quite a big bottom though. Hates anything bulky round her middle. About a size 14. I am really quite desperate now to find something she will accept that she can change into. Any ideas of a reasonable alternative? Thanks in advance again!

@stressybetty good luck! I thought I would get away with removing a torn (very)old jacket that mum insisted was the only jacket she would wear. I was sure she’d forget it, based on a couple of previous successes and substitutions. No, she went on and on about it claiming it had been stolen, it was being sold - she was going to claim on insurance - I felt dreadful for the two weeks or so it took her to forget. Some of these things are very … idiosyncratic!
