Great winter staple

Does what you want as a medium warmth essential that looks good too. Quite long in the body, I’m 5’1” but that’s okay tucked in for extra warmth. Have this in animal print also which is fab

Medium Thermal Crew Neck Top

No, I don't recommend this

I bought 2 supposedly identical items: same style, size, colour etc. I often buy 2 of the required item because of the wide variation in fit and length with M&S clothes which are meant to be identical. One of the tops had sleeves which were about an inch shorter than the sleeves on the other top but the length of the top was much longer than the other top. I will keep one and return the other. The quality of the tops was good.

Perfect!

Yes, I recommend this

Absolutely love these tops. Fit perfectly, snug and toasty warm. I wanted some thermals that I could also wear as basic tops in the spring and autumn and these are just what I was looking for.
