pinch free support

Yes, I recommend this

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.

Not that warm

No, I don't recommend this

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.

Lovely shaping vest

Yes, I recommend this

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

Yes, I recommend this

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

LOVE it

Yes, I recommend this

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.

I like it

Yes, I recommend this

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

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??

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.
