Brilliant Shapewear

Yes, I recommend this

I love these waist cincher knickers. They're excellent quality, really comfortable to wear all day, don't roll down and keep everything firmly in place, giving me a great silhouette.

Great product, good price

Yes, I recommend this

Bought to wear underneath an occasion dress. I am a size 10/12 at the hips/waist and bought both the size 10 and 12 for click and collect. The size 10 fit well - snug but smoothed the stomach and 'saddlebags' areas well. Really glad that I was able to try both on upon collection and return the size 12 immediately. I don't think other shops necessarily offer this option when ordering online (often there aren't any relevant sizes in stock, so you're taking a risk by ordering without trying on first especially with shapewear). IT wasn't uncomfortable for the whole 10+ hours of wear. I have a short torso so the top seam rolled down a bit where it met the bottom of my bra, but it wasn't too bad. Can't comment on VPL as my dress wasn't clingy in the bum area. Since washing the seams haven't frayed so I think it will last a while, but would recommend putting it in a mesh bag to avoid snags. Overall happy with it and felt the pricepoint (no discount) was reasonable for the job I wanted it to do.

Think About What You Need

Yes, I recommend this

The body shaper is effective but it will only smooth your outline around the belly. It will not eliminate all the unwanted bits eg. It can look smooth below the bust, but then push the excess to around the bra line which defeats the object. If you're worried about the whole torso, your probably better off buying a full body shaper. Also, if you just buy your regular size its a bit of a push and pull to get it on. So I suggest you go up a size to make it as comfortable as possible, but you might find it slips a little. Depends on your needs but I think I'd go for a full body shaper next time.

Not impressed

No, I don't recommend this

The top doesn't stay up, as soon as you move around, it rolls down.

Fits the requirements

Yes, I recommend this

Bought to wear under a new dress for my daughter’s wedding in March ‘26. Seems to be good quality although fit on me isn’t perfect but that’s down to my body shape. Fits where it’s needed but gapes around leg line as I have skinny legs and no bum haha

Almost perfect

No, I don't recommend this

It's a tight fit, but really smoothed out my shape and gave me a waist. It rolls down at the top. The rolls felt like it had cut off the circulation and was so tight, it left bruises. However. I looked fabulous. I'm going to buy the body suit in the same size. This should solve the rolling issue.

Excellent shapewear which didn't roll down!

Yes, I recommend this

I purchased these control underwear for a wedding I was attending. I had a dress, but wasn't happy about all my lumps and bumps around my tummy area. These knickers smoothed out my tummy and hips, and made me feel far more comfortable and confident in the dress. They didn't roll down at all the whole day, which I was slightly concenred about them doing. Would highly recommend.

I had to laugh

This was extremely tight although I sized generously. It immediately started rolling down at the top, creating new lumps and bumps I didn’t have before. It was incredibly uncomfortable and did nothing for me. Total fail, but I had quite a hilarious struggle with the thing. M&S should offer a recycling service for everyone who buys these and wastes their money. There must be a mountain of them.

Twelve hours wearing and comfortable!

Yes, I recommend this

Ordered size 16. My shape is hour-glass, I wanted firm control for a smooth silhouette in a long velvet dress (wedding guest). They did the job. I wouldn't say they had a waist-nipping effect, though they did smooth everything out. I found them comfortable, they did not ride up on my bottom or roll down from my waist, and I had been wearing them from 11am to 11pm approx.

I bought it to go under a figure hugging dress and it smoothed out the lumps and bumps that had been worrying me. It didn’t roll down and I wore it with confidence.

A Really Good Item

I bought this to wear underneath the beautiful skaters dress I bought as I sadly no longer have a waist. It made such a difference and was comfortable to wear and stayed in place I’d highly recommend

Nice but with wear becomes uncomfortable

Bought to wear under dresses and jeans, but it rides up your bottom when you walk. I felt quite self conscious because it gives a terrible vpl when half of your buttocks are in and the other half is riding out.
