Great thigh slimmer but…

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Great product for slimming thighs and giving a smooth torso without feeling too constricted. The thigh length is adequate resting just above the knees. However I have not given the full five stars due to poor quality stitching around the cotton gusset. I am a pear shaped size 12 and went for the large size. I’m having to replace with a new pair every month. I’m now on my third pair with the same issue and thinking of trying the extra large to see if that makes a difference.

Great sizing, shape and control. I’m so happy with my purchase. They were comfy and did not roll down

Perfect, did the job I wanted them to do and had a decent length in the leg. I was expecting a huge battle to get them on but they were surprisingly stretchy and easy to pull up

Firm support, comfortable, light & breathable for all day use. I bought my usual size & does the job perfectly. I didn't have any roll down, it stayed put. Love it.

Why size them so small

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

I don't understand why M&S size this product so small. I got a size bigger than my dress size, I don't have fat legs and couldn't get these past my knees. Just a complete waste of time for everyone. Why?

Fairly easy to get on and off, stayed up and ‘smoothed’ my lumps.

Great price and great fit

Really impressed with these, especially at this price point. I'm a 10/12 so I ordered a M and a L to compare sizes. The M was way too small for me, but the L fit perfectly, with the legs coming down to just above my knees and the top finishing at my under wire. The body did slip down a little bit whilst I was wearing it, but overall it was very comfortable, lightweight, and breathable.

Does what it says on the tin! I took them out of the box and thought they would fit but they do and look really good. Don’t roll down and I could still breath. Would recommend

Bought this to smooth out panty lines and hold in my tree trunk thighs! I’m a size 14 but could not get the medium past my knees so went for a large size. Much easier to get in but still does the job! Very comfy too, even during our May heatwave. So I bought a second one!

I ordered a few but this was definitely the best. Lovely fit and didn’t roll down. Felt great under my dress and great price too. Highly recommended.

Not for me.

Good control, comfortable, but due to the strange shape on the bum, I had to return it. It basically gave me double bum cheeks.

Not as thick as the more expensive one. And definitely longer which is great! Loving the longer length! Got the Large. I’m a size 14. Do NOT size down!

I’ve ordered different types of shape wear from different shops and none of them have been anywhere near as good as these! These are comfortable, great control and don’t cut into you like other pairs!

Good quality just didn’t fit me. These would perhaps be good in a bigger size. I am quite hippy/thigh with small waist
