Try before you buy

No, I don't recommend this

Quality is good but the sizing comes up smaller than usual sizing? Not the most comfortable

Great vest

Had a couple of these a few years ago and great for the winter and good upper half shaper. Therefore I was glad to see M&S have brought them back, a white version would be nice

Nice useful vest

Yes, I recommend this

A close fitting vest for wearing under blouses or cardigans is such a useful item and I am looking forward to wearing this. It fits well but I have yet to wash it. However, knowing M&S quality I have no concerns.

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.
