Why have you stopped these?

Yes, I recommend this

They are brilliant. I've got loads but need more as I wear them everyday. Why stop making them when they are so popular with such great reviews? Why stop doing the things you do well and that people expect and want from m&s?

Soft, stretchy, comfortable, thin, tight!

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Very thin fabric - even translucent. Not particularly warm despite being Heatgen! Nice shape though, comfortable and stretchy, goes well underneath other clothing, though very skintight - particularly clingy under the arms which isn’t ideal. Also, I ordered a size larger than I normally wear and it was still far too tight! Soft fabric, nice and stretchy and a good shape, but much too thin for something supposedly thermal, and much too tight.

These tops are light, warm and stretchy and are good all year round (summer too in Scotland). Really good value for money. More colours please!

Have several of these useful tops

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

These tops are useful and generally last quite well. My criticism (as other's have mentioned) related to sizing. Normally, I take a size 8 in most makes of clothing but with these tops I have to buy a 12 or even a 14. The larger sizes are still not slack on me, not are the shoulders too wide. Size 8 is positively uncomfortable ... and certainly not flattering. That said, now I know what to expect, I just buy larger .... making it hard to answer the QNs below ... I bought a 14 because I know this will fit me properly ... but I am really a size 8 .. so I amswered below that its fit is small .. which it would have been if I'd bought the correct size ..... errrr ....

Comfortable and warm

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Bought a couple a few months ago and liked them so much that I have ordered others from the range, in different colours. They are made of a soft, stretchy fabric and are great for layering under shirts & cropped jumpers. The material is quite thin and a little see-through, but this makes them more attractive under dressy tops. Hoping to continue wearing them right through to the summer. Would like to see a wider range of colours, such as wine and dark green.

Lightweight

Originally posted on marksandspencer.com (UK)

A lightweight longline top. Quite thin but still effectively warm. Paired this with the leggings. Slight bobbling only downfall. I probably would of returned if I wasn’t in need of them, due to the transparency. Apart from those downfalls, overall very warm!

Fabulous top

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I bought 2 a few weeks ago. One each for me and my adult daughter. I have about 4 already but she was thrilled with her first one. She feels the cold and immediately felt the thermal warmth - wears them every day under jumpers etc as they are not at all thick or bulky - more like a second skin. True to size. I have the slightly shorter versions too.

Cosy and warm

Originally posted on marksandspencer.com (UK)

After a few washes the stitching on the cuff of the sleeve is all coming undone...stitching is of very poor quality.....very shabby.....very disappointed... I would have taken it back to the store for an exchange during normal times but due to Covid I am not venturing to any non essential shops.

Perfect length

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

These are described as long line which is the only length to buy your tops in as far as I’m concerned. These thermals are perfect underwear as they are in no way bulky and sit comfortably against the skin. I wish M&S would do more vests and tops in this length.
