Ladies thermal tops.

A litle snug, but good arm and body length. Unfortunately thicker than I would prefer for a layering thermal top.

Good quality but I’m taking no chances - it’s NEVER going in tumble dryer. I’m fed up with M&S items shrinking!!

Poor service

Originally posted on marksandspencer.com (UK)

I was looking so forward to receiving this garment as I already have several of these which are fabulous tops warm , and wash well the quality is excellent but I was so disappointed upon opening this top as I had ordered a brown one my account shows I ordered a brown one the cardboard sleeve which the top was packed in even said in clear letters BROWN but the top is a very nice cream colour how disappointing also it is plain to see that something is amiss with this order as the top itself was scrunched up and forced into the sleeve almost as though the person packing this garment could easily tell the cream top should not be packed in that sleeve ,I could not bring myself to make the journey to a M&S store it is a great effort for me being disabled my gripe really is about the mistake I like millions of others through out the world are absolutly crushed with having to rectify the careless service that we are subjected to us from many different angles I’m a very unsatisfied customer at this present time .

I don’t wear this for as undergarment but as a really cosy top with my jeans/trousers and also under my ‘walking jacket’! Great value too!

Lovely warm and useful tops

I have these tops in many colours. I wear them most days with trousers and pinafores. They look particularly nice paired with trousers of the same colour. They are warm and wash extremely well. Every time i see a new colour i buy it. I i have tried different necklines but my favourite is the crew neck.

So comfortable

Originally posted on marksandspencer.com (UK)

Material is nice and stretchy and did the job of keeping me warm. I will say it did bobble after the first wear but this is more of a layering piece for me so not a major problem. Also because I got the cream it was a little bit see through but if you have a nude bra it wouldn’t be seen.
