Very poor quality/ there is no elasticity and the cloth used is very poor. I threw them away.

Extremely Comfortable,

Originally posted on marksandspencer.com (UK)

I was a bit iffy about how comfortable these knickers would be as they looked to be really high on the leg.However I’m finding them very comfortable.I love the material which is so soft and silky, that I hardly know they’re.I also liked the colours but comfort is my main concern and these deserve 5 stars for that.

Disappointing

Disappointing. I was hopeful that these would be a great fit, comfortable when exercising. I bought 2 x 3 packs, wore one for the first time and realised that they were far too loose and didn’t stay in place.

Poor Cut

Originally posted on marksandspencer.com (UK)

I was disappointed with the cut of them. I always buy M&S knickers in the same style and size. These don’t fit well. I would have returned them, if I hadn’t taken 6 pairs on holiday

So glad I bought these knickers, not only are they are great fit, I have a bit of a tummy. They are soft and comfortable and don’t ride down when you are active. Perfect size 12.

Disappointing quality and comfort

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

I bought some of these about 3 years ago and loved them, fitted well & were very comfortable. So this time I confidently bought 4 packs, however when I unpacked them they didn’t seem to be the same quality as the previous ones and having worn them am very disappointed in the fit they are very flimsy in comparison and sadly no where near as comfortable.

I really like these. Smooth, comfortable, nice shape. They wash and wear well. My only quibble is that i wear with the modal Flexfit bra, which seems to be the obvious matching product, yet one is opaline and one is rose quartz.

Good quality, just not a great fit for me

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Sadly, these aren't a good fit for me. They slip up my backside more often than not, and under my middle aged belly. Making them somewhat unconfirmed. I'm sure they look wonderful on a slim jim, but that's not me. 😏
