Size up !

Perfect, I knew to order big. Im a size 14 but ordered a size 20 and its very comfortable. Size 18 would probably have been ok but it was out of stock. But still comfortable in the 20. Its supportive without being too tight, will be great under a light blouse.

Cosy and supportive

Originally posted on marksandspencer.com (UK)

Holds you in nicely in tummy, waist and hips. It's also quite cosy.. The scoop neck doesn't show under a work nlouse. I have the short sleeve version too.

pinch free support

MY favourite purchase to date when it applies to shaping vests. I have been wearing bra support vests but this style is much better especially in the cold weather. I am a size 18 so bought a size 20-22 which has proved ideal as it is very comfy to wear and does not pinch but still me in place. I knew the 16-18 would be too restrictive for my shape. No need for a bra either . very quick and easy to wash and dry. I use it most days at the moment. I now have two of them and might buy another. I wish there was a white or cream version in this style.

Comfortable and warm. Would be nice to also have a white version. At the moment only seems to be available in black.

Can't say I've noticed much thermal property about this top. Very squeezy in terms of sucking me in, but that wasn't why I bought it. Disappointed.

I love this shaping vest. I’ve recently had abdominal surgery and this vest is great to feel supported but not squashed! I’m definitely going to get another one.

Flattering Shape

Flattering shape so can be worn alone or discreetly. Thick thermal material, would have preferred slightly longer length but would still buy again

I LOVE this Heatgen Thermal Light Control Shaping Vest. The fabric is firm enough to smooth out unsightly bulges and it's warm. A pleasure to wear this winter.

Good under garment. Provides that extra layer as it gets colder. Fits snugly.

I bought this as i thought it might help with a muffin top as well as keep me warm. I can report that it definitely smooths things out, and is comfortable to wear. I still have a muffin top but its more contained!

Much too small and a very tight fabric

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

I was truly shocked at the very small size of this top - I am typically a size 16 blouse but sometimes buy a size larger for a loose fit, so this top in size 16-18 should have been OK. However, it was so small, and the fabric so inelastic, that I gave up any idea of squeezing into it for fear of not being able to breathe or get it off again! I have never had such a bad experience! Perhaps the labels were incorrect and it should have been a 6-8 size??

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.
