I don’t like the fact that M&S is using stick thin, 6ft models, when I am only 5ft 1in and not fat but not stick thin. It totally mis represents what clothes look like on the bodies of many older women (the majority of their customers). No wonder so much stuff is returned, which increases the price of the clothing.
Having said that I still think M&S beats other shops of a similar price range, for quality and longevity of wear.
I cleared quite a few things out of my wardrobe and was horrified at the wastefulness of previous, often random purchases, so have decided to be more disciplined in future buying. To buy fewer clothes with consideration of how much wear I will get out of each garment, cost per wear rather than purchase price. I won’t be buying the jacket shown on the OP that’s for sure!
