Grandtante, I have the same problem with synthetics. It's really a pity as natural fibres look better anyway, I think.
Jalima, I completely agree with your DH. Quite ordinary High Street clothes used to be made with the basics of tailoring in mind and it made all the difference.
The way clothes are cut today is bizarre. I know it sounds grumpy but I look round and I see about 90% of people in clothes that don't fit! It seemed to start when manufacture went over-seas. (Pretend I didn't say that as I know this wasn't meant to get political! Sorry.)
M&S really do need to pull their socks up. As for the models, there seem to be two sorts: miserable 15-year-old starvelings who need suet puddings fed to them daily, or women who are overweight (supposedly more 'true to life') but do at least have the advantage of being adults. The 'curvy' models today don't look like actual people I know. My normal-size friends look just that - normal. And healthy. Not fat. Don't feel bad when you see the Amazon pics, etc. as you probably don't look like them at all.
Varian, that's quite a good idea for finding models. I see people on the street every day who are far better looking, and much more stylish, than the ones earning fortunes.
As for my own body, my bum apparently got very sad about something a few years ago. Just silently sank down to the tops of my thighs and refuses to be cheered up!
