Perfect

Yes, I recommend this

Purchased to wear under a fancy cropped jacket that I am scared would come undone. However fits perfectly, cosy, smoothing and comfortable. Will use under many outfits.

Winter staple

It seems like the shaping vest is going to be a staple for cold days when you need a layer under party garments. The vest does reasonably well the shaping function because it completely covers the stomach area. As for me, it is true to size (large bust). Wishing for a natural colour available in the near future.

You can't beat the M&S heatgen thermals. There's such a variety of styles now and the colour choices are great this year. I highly recommend.

Comfy wear

Yes, I recommend this

As I was in need of a bit of shaping I thought I’d give this vest a go. I was pleasantly surprised to find that it didn’t roll up like bottom up shaping has a tendency to do. Easy on, very comfy but a little more difficult to take off, think I need to work on my removal technique.

Didn’t realise that this vest was light control, I loved that it was light control and didn’t roll up when worn

Great combination of thermal & shape-wear.

Yes, I recommend this

Great to have both thermal and shape-wear in one garment. I wore this under my wedding dress as it was cold in February and I wanted a little smoothing out too. It also meant I didn’t have to worry about the wrap dress being too revealing. I ordered a size larger than usual as other reviews said this came up tight, and this was the right decision (my usual size was sold out anyway).

Warm, Soft top and perfect for cold weather.

Yes, I recommend this

I bough this for a trip to Austria and I’m so glad that I did. It is very soft ; warm and comfy. Perfect for chilly weather and quite a pretty top. You would never know that it was thermal because it was a nice styke

No, I don't recommend this

Very tight-fitting, had to size up. Not for me, I found the material made me very sweaty.

Nice vest

Yes, I recommend this

This is a nice vest but not quite what I expected. The style and make-up is great, but the thermal I thought wasn't there. I expected a nice warm material but I did not find it warm enough to wear in the present cold conditions. The support is pretty much noticable in wear but I am a size 12 on top, no more no less, and I found the size 12/14 quite "compressing"! I'm not sure it would fit very comfortably for a person wanting a bigger size.

Supportive top

I bought size 16 -18 although I’m pretty much nearly always an M&S size 14 and found it to be a snug fit, glad I opted for the larger size. I would describe it as medium control rather than light control and quite a thick fabric.I use it under other garments.

Great

Does what it says on the tin - warm and lightly holds in some lumpy bits. One plea could you manufacture this is white or cream?
