Really soft and beautifully warm to wear.

Yes, I recommend this

This thermal top fits so well. The soft stretchy material traps in the natural body heat and keeps you so warm. I am going to buy several more ready for next winter. I have washed the top and there was no shrinkage.

Crew neck top

Yes, I recommend this

Have bought these for the past few years and they are amazing. I have took them off one star because they no longer do the scoop neck, which I usually bought. Also could not get them in navy lots of other weird colours but not a basic navy. Do wonder who designs this stuff sometimes.

Bought on behalf of a friend currently living in a care home. She was very pleased with the item and finds it keeps her warm when worn with PJs.

Cosy and good quality

I have bought these before and have loved their cosy feel. However, they have changed the neckline and instead of a soft scoop it's quite high. Personally, I don't like a high neckline and find it annoying! However, other customers may prefer this change.

Warm

Ideal winter weather tops look good with or without any further jumper. I go for a size up only because don’t like clingy tops show too many bumps.

Great Basic T

Yes, I recommend this

Lovely and soft and comfortable. I keep thinking the m&s tops have lost their length a bit in the body. Im 5ft 5 and could do with being just a tiny bit longer. Nevertheless would buy again.
