A close fit

Good quality but please, you Must go back to numeric sizing!!!! There are less sizes now and XLonly just fits, when my normal size top from you is 18 or 20. What about us larger-on-top ladies, who you seem to be slowly alienating in the name of high fashion.Very disappointing.

Bought in anticipation of colder weather. Lovely and soft, not too thick so useful as the weather gets cooler. Good for layering.

Very tight!

I've been a size 10/Small for years with M&S so was really surprised when trying on one of these tops to find it so tight, it's more like a second skin and would fit a child better. I'm hoping with wear it might stretch a bit (fingers crossed) but if not will pass it to smaller family member.

Order at least 2 of these every year for daughters Christmas. She loves them but always wants a couple that are nice warm colours. These will do nicely

Not up to usual sizing standard

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

I ordered the XL which is usually too big for me, because of the stretchiness. Unfortunately, they’re much too tight. Even tighter than the size 22 I bought in the spring. But I’ve broken the pack so I guess I’ll have to keep them. They’ll go to the charity shop. What a waste of money.

Great, although not sure why the sizing has gone from individual sizes to size ranges. Im a 8 so now buy small, rather than a size 8. Fit is Perfect as a base layer in the winter.
