Warm, soft on skin and long.

Yes, I recommend this

Love these. I bought two. I hate the cold and I get very sore, itchy skin. These are lovely and soft on the skin, warm but not too warm and the best bit is the length which prevents the back riding up when tucked in. I will buy more. Size medium -I'd say 12-14 comfortably.

Toasty warm vest

Yes, I recommend this

Bought this strappy vest to go under a jumper so that it wouldn't show at the neckline. It super warm with a soft thin fleece on the inside. True to size.

Alternative option

No, I don't recommend this

I bought this as the one I really wanted was out of stock - it has long sleeves and lace edges! The one I really wanted I have to size up, normally a 10 so bought a 12 but no need to size up in this. It does the job but the body section is really long so not ideal if your 5 ft 2 - will still use it but not 100% what I was looking for. It is good quality material, thick and warm.

Warm & comfortable a great addition my wardrobe

This vest is long and warm and thin enough to wear under a blouse or jumper without being see through. I have worn it almost every day since I purchased it. My only negative comment would be that it’s not as chocolatey a brown as M&S tights but still looks fabulous.

Disappointed. Far too long in the body making it bulky to tuck in.
