Fab thermal top

Yes, I recommend this

This is a fabulous thermal top, warm and cosy but sparkly too so you don’t mind it showing beneath other clothes. I’ve bought a second as it is such a great product.

Great Thermal Lawyer

Yes, I recommend this

I bought this to stay warm as I was going away for the weekend and only wanted to bring a jacket, It was just the right level of heat, kept me cosy and to be honest I have been wearing it every since. the scoop neckline means you don't see it under a blouse. Washes well and although its says do not tumble dry it has been and its turn out fine.

Perfect Thermal Top with touch of Sparkle

Yes, I recommend this

Perfect thermal top (black sparkly) for dressy occasions if expecting venue to be cold, ie cold restaurants. I ordered size 12 which fits perfectly. I have also ordered one in cream.

Love the sparkle, a bit thick though

Undoubtedly very warm, and a nice design but surprisingly a lot thicker than expected. I have a numberof M&S HeatGen turtleneck tops, so was expecting that fabric on this item. However,m it will certainly be a cosy addition to my winter wardrobe.

Lovely quality thermal top

Yes, I recommend this

A lovely quality top which has kept me nice and warm on these cold winter and early spring days! Although it is nice enough to be worn just as a top, I've been wearing it as a vest. It washes really well too and still looks like new! It's so nice and comfy too!

sparkle choice

Yes, I recommend this

another in a long line of thermal tops that I now have in my wardrobe. I wear these around the house and when I am out walking. quick and easy to wash and dry. They will last quite a few seasons. This black sparkly one goes with the sparkly leggings I bought so will suit relaxing party outings , Xmas laziness and could be dressed up with the right shawl, cardi, or kaftan. Very affordable top, especially this time as it was in the sale
