No, I think whoever earlier who said that they are trying to appeal to the edgy but doing it wrong was correct.
M&S are never going to to be edgy and they need to stop trying to be. If hipsters want leather dungarees/shirt dress, they will not buy them from M&S. They will buy them from some uncomfortable pop-up shop in Hackney run by a bearded Swedish person in fishing trousers.
Just give us nice basics, FFS! No sequins/beads/lace, no embroidery, normal person sizes, not purple and stuff that we can actually wear!
