You're right Jane10, the new cotton just isn't the same. Their supima cotton bedding also dropped in quality before it was discontinued.
I buy various styles of pants including their cotton shorts and wish that they would be a bit more adventurous with colour. They do lots of coloured pants with rather dated patterns. I prefer plain but their colour range is limited - perhaps they only do colours which go with their own bras? I don't wear their bras as they don't fit/support me well despite using their fitters.
Whilst on the subject of M&S, I wish that they would do simple, plain pure cotton pyjamas without cropped legs. I don't like the sets with T-shirt tops, or jersey, or indeed the nightwear styles they do in general.
I've also tried in vain to find a cream v-necked jumper - the necks are all so low that you need something underneath them. They used to do lovely (thicker) cashmere, now it is thinner, perhaps that is why I can't get cream as it is transparent?
In general just wish that they would go back to selling excellent quality, simply designed clothes.
