Warm and cosy and yet still stylish top.

Yes, I recommend this

I love a thin top to layer under a sweater, this one is attractive enough to wear as an outer item, it's comfortable and I like the gingery colour animal print. It keeps me warm without feeling bundled up?

Thermal top

Yes, I recommend this

Lovely product, a little snug but that’s not a problem underneath other tops as I plan to use it.

A good buy but watch the sizes as they vary

Yes, I recommend this

I have a lot of these thermal tops which I wear constantly throughout the colder months. They usually fit well wash well and are very comfy. I bought this one in the sale. It fits well around the bust and shoulders but is a little tight around the stomach and hips.

Yes, I recommend this

I absolutely love these Heatgen tops. I bought size 8 (this is my usual size) and it fits perfect. I have quite a few but M&S don’t do a big enough selection anymore otherwise I would have purchased more

Bad fit.

Size 16 was ridiculously tight. Struggled to get my arms into it. A shame as the other colours are true to size?

Thermal long sleeve top

Comfy but not especially warm. Bit too long in the body & sleeves too long.

Absolutely brilliant and perfect item.

Yes, I recommend this

This top is extremely comfortable, easy to wear and wonderfully warm. I am actually wearing this to on its own, with no need for a further layer.

Very very small fitting,order up a couple of sizes

No, I don't recommend this

I’m usually an 8 but they looked quite snug fitting so I ordered a 10 and an 8 just in case. I had to send both back as I looked like a trussed up chicken even in the 10. These are so tight they show every lump and bump and even worse, I’m pretty slim but looked like I had rolls of fat…and that was just when I was stood up, I didn’t want to see what it looked like sat down. Not for me I’m afraid, you need to order at least 2 sizes up.

Thermal Top

I am normally size 12, but after seeing reviews that indicated the top was skimpy, I ordered a size 14 - I will normally wear it under a gilet or cardi, so it needs to be comfortable, rather than a good fit. Pleased with the top.

Yes, I recommend this

Love this top but small for size it is. More like a 10. I wear it for bed so its ok but could be worn anywhere. It is a lovely top and would go lovely with pants and jeans. I bought 2 and kept both and wear them both a lot under sweatshirts.
