Lovely idea but it’s not long enough in the body for me. Does the job though, but I needed to keep pulling it up.

Comfortable and high quality material. Great value. I wear these with my bodycon dresses these days as have gained some menopause weight. These made me feel more confident and less self conscious.

These are great. Comfortable and give a great shape. No roll down on wearing. I've had one pair come apart at the gusset, though.

I was worried this would roll down at the top but it stayed in place just fine! Used for a wedding and was very comfortable - size 20

Really useful for helping deal with a Spigelian Hernia. Washes well and keeps its shape.

You need to order a size bigger

Originally posted on marksandspencer.com (UK)

I bought this to wear under a dress for my nephews wedding. Unfortunately it was too small, so I couldnt pull it up over my belly. The next size up would probably have been a better fit.

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

Originally posted on marksandspencer.com (UK)

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

Originally posted on marksandspencer.com (UK)

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.

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

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

Originally posted on marksandspencer.com (UK)

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.
