You see me rolling…I’m hating

No, I don't recommend this

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!

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.

Order up several sizes

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.

These worked great to smooth things out under a form-fitting dress. A bit tricky to get on and off for toilet trips but that’s to be expected of shapewear!

I made a brave and bold decision to buy this product and in a size smaller. I really want to look toned in my Xmas outfit.

This did the job - definitely smoothed out the bumps. It’s a little tricky pulling it back up under a tight dress after a loo visit.

Sucks everything in, but assumes you have no backside, so comes up quite low on the back
