Shaping vest

Yes, I recommend this

Bought my normal size but had a struggle to get it on as so tight but once on it is very comfortable. Holds you in at all the right places and is very warm. Doesn't ride up so would definitely recommend.

Very good Thermal vest.

Good thermal vest, really hugs the body and helps hold in the midriff too. Lovely and warm and comfortable.

Great quality. Warm and cosy.

Yes, I recommend this

I love this top. It’s great quality. It’s a little inflexible when putting on, but it’s so comfy and warm when on.

At last some decent shaper vests from M&S

Yes, I recommend this

I’ve been disappointed by the lack of shapewear vests in recent years. These are good quality and comfortable. I wish M&S would make some similar to my old favourites which had an under layer of firm mesh fabric and a top layer of jersey, they were amazing and I’ve never found any better. M&S also used to make shaper tops with an underwired built in push up bra - not the basic ones they now sell but lace on top of a firm base and transformative but comfortable. Please check out your old designs from 20/25 years ago as they were the best ever. Nothing available from any brand comes close. I’ve waited years to say this and I hope one of the designers reads it. Ps I bought two of the vests and will buy more.

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

Yes, I recommend this

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.

Perfect

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.
