Not for me

Fits ok, but rolls down as soon as put on, so really uncomfortable

Roll down rollercoaster!

I’d read previous reviews and bought a size 16 instead of a 14 which was the right decision. I’d bought it to wear under a dress for a wedding and thankfully did a trial run wearing it under a work outfit one day. However, it rolled down regularly and really was a waste of money. I’ll stick to no VPL pants and firm fitting tights, they seem to do the job just fine!

Great pull in!!! Smooths out all bumps. Stayed in place, did not roll down. Felt very secure. True to size & very comfortable.

So comfortable for shape wear, easy to get on and off and stayed in place.

The only one which did what I wanted it to in terms of pulling in my tummy. The fact it comes up high to bust line stops bulges coming over the top

Not a good fit

Originally posted on marksandspencer.com (UK)

Tried on 2 sizes which unfortunately didn’t fit right. The size 10 ( normal size) was far too tight and uncomfortable. The larger size fit however rolled down and not so supportive around the thighs

Bought these to help smooth those bumps under my dress for a wedding. Haven’t worn them yet but have tried them on and looks like they will do the trick.

This is a great shapewear garment. It stays put and gives a nice smooth shape for dresses. I sized up one size so it doesn't roll up when its very tight. Its still firm and holds you even when you size up. I got a black and a nude

I brought both my size and the size up but they just kept rolling down at the top so unfortunately had to return them.

Amazing!

Originally posted on marksandspencer.com (UK)

Very comfortable but also do the job, brings you in at the waist and smooths tummy/legs. Perfect for a slightly fitted wedding dress and better than leading shapewear brands.

A great quality product but size up one size

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Really supportive!! I read the other reviews and sized up and they were a perfect fit. They really helped with the love handles and helped me feel firmer round the tummy although they did probably pinch a little too much around the seams of the legs but thankfully my dress was below the knee so this didn’t matter.

I wear a size 10 trouser in M&S and ordered a size 12 for comfort. Couldn't get them over my knees. Either this one is faulty or I need either a 16 or an 18.

They aren’t confortable and the fabric is too fine so don’t support well and keep rolling down. It is a shame!

Really pleased with this Magicwear waist cincher and thigh slimmer, which I bought in a dark brown shade. It smoothes out those lumps and bumps and is comfortable once you have it on. Useful under trousers and midi skirts.

Brilliant, I’m a 14 but got the 12 so it would suck me in more. Fabric nice and strong!

It's, ok

Originally posted on marksandspencer.com (UK)

Being a now menopausal female, this garment, yet again, is too tight at the top elastic due to the delightful new weight distribution that I'm fighting daily. I would have gone up a size, but then I would have no support from the rest of it, it would have been far too big. Please M&S can we consider the changes in body shape that are experienced? I will have to remove the current elastic, source similar and sew a new top. Luckily I can sew, many others wouldn't be so lucky.

I bought this to go under a LBD, but the top rolled over every time I moved, and the legs were a little too long considering I'm 5' 10". Not easy to get on/off. Certainly didn't flatten the tummy at all.
