I wear these tops every winter and never want to take them off , I couldn't do winter without them, utterly brilliant! No other brand comes close in quality or warmth.

Sizing all wrong

Good material but SO undersized unless you want it to cling

Perfect

Very cosy & does the job perfectly of keeping the chills out. I wear these during the day in the house under looser clothes. It keeps the chills out so I can delay putting the heating during the day. I love M & S heatgen maximum products; they do the job well. I’ve been wearing these various heatgen products for a couple of years & have no negative comments to make on them.

Not up to M&S normal standard re sizing

Originally posted on marksandspencer.com (UK)

Sent back my normal size is 18 bought large, way too tight. Having been buying these over the years never had a problem previously. Returned. Hoping the X-LARGE will fit. Really don’t want to make further returns. How are we supposed to know what S.M.L.XL are? Please return to Normal sizing.

Awful sizing

Awful sizing. I’m a size 20 and ordered the largest size based on the size guide and it’s way too small. I would say more of a size 14-16. Disappointed and made me feel like rubbish. I do not recommend this top

Lovely design but slim fit

Originally posted on marksandspencer.com (UK)

I really like this top, the design is nice and it is warm, but the sizing is definitely on the small size and you are well contoured even if you size up which I did.

Good looking tops for colder weather

I have most colours of these heatgen tops, find them great for under other tops for cold days but stylish enough as a top by itself.

This is great but too thick for me - I returned and bought the lighter weight one
