Favourite knickers!

Yes, I recommend this

So comfortable yet flattering, and they last really well, it's hard to beat the quality of these.

Very bad fit

No, I don't recommend this

These don’t fit well at all - the flexi part simple means ‘ride up’ all the time. Almost from the second I put them on I just knew they are going to be massively uncomfortable. I will know to avoid this kind of design in the future. I have a flat, shapeless bum and I don’t know if this is why they don’t stay put? Bought for the colour as usual style is high waist high legs which only come in black in my size. Actually really disappointed I am stuck with 3 pairs of these, 1 worn once and 2 which will just sit in the drawers never worn, gathering dust!

Great pants, if you don't mind black

Yes, I recommend this

I really find these modal knickers comfortable and would recommend them. But... I am a size 22 and sadly all colours apart from black were unavailable, and have been unavailable for a while, which is a huge disappointment, as I have the range of bras in 3 colours. I'd buy the 4th bra in magenta if it was in stock along with the pants. Please get some stock of these items soon.

Very disappointing product

I read other reviews and bought a size down (6) however the pants still do not stay in place. Totally ride up into the crotch area as well as the back. 1 star as the material is soft however the product does not deliver on its purpose.

Terrible fit.

No, I don't recommend this

These are a terrible fit. They don’t give enough coverage at the front and do not stay put at the back

Nice but don’t stay put

I bought my usual size 12 and these fit pretty well but they don’t stay put. I think it’s because they are a nice slinky material with little elasticity, also I’m bigish in the tummy and narrow of hip so the waist band rolls over and the bottom bit is not gripping to my cheeks. I haven’t had this issue with other M&S knickers before.

Supersoft But Substandard Stitching

Yes, I recommend this

I have these in black and rose quartz colours in size 12 - went for this size rather than 10 as I’m often in between sizes depending on colour and these are just right. They are very comfortable and soft, (much better than the M&S cotton ones with lace tops which have too-tight leg holes which rub). I have dropped a star because I was disappointed with the quality of one pair of the beige colour briefs, which had a stitching fault on the outside gusset area, with threads all pulling undone and I have had to re-stitch this bit. I have read other reviews mentioning this problem, so M&S need to address this quality problem.

Too stretchy

No, I don't recommend this

Bought to wear at night with secret support vest top. These don't cover the bottom area very well and are way too stretchy so get twisted up and don't stay put

Comfortable.

Comfortable, stretchy and don't dig in. The only thing is, the gusset is very small. Could do with some more coverage.

Comfy but get out of shape with wear

Comfy at first, but get out of shape with wear. Nice colour ( (Grape) and soft fabric. I ordered a 14 expecting them to shrink a little in the wash but instead they seem to lose shape and structure whilst wearing and you spend your whole time pulling up!!

Excellent

Yes, I recommend this

I like these pants because they are very comfortable. I find them a little on the large size but they wash well and like the matching bra I don’t even know I’ve got them on. My big beef is they don’t do the green colour.

High leg pants bought to match Bra

No, I don't recommend this

Lovely soft material - fit doesn’t seem to be the same as other M&S high leg - very cut away at the front & skimpy at the back - not such a good fit in the same size I buy other high leg packs - just hope they keep their shape & don’t shrink
