Unhappy

Originally posted on marksandspencer.mom (UK)

Lovely soft fabric, pretty colours, to match my lovely flexifit camis, had high hopes. I’m a 10-12, got a 12 as I don’t like undies too small. However, these migrated upwards, inwards , horrible fit on me and put in bin. Might try the high waisted shorts version next

So comfortable and they don’t toll down. Would definitely advise to size down. Lovely product.

These knickers are so comfortable but not so happy about the quality of them have threads hanging down so wonder how long they’ll last

Disappointing

Originally posted on marksandspencer.mom (UK)

I’v been wearing these for years, but the last ones I bought are a disappointment as it doesn’t stay in place and the material is worse than the previous ones.

Perfect postpartum / post c-section knickers!

Originally posted on marksandspencer.mom (UK)

Yes, I recommend this

M&S is always my go-to for underwear. I bought these specifically because they’re high waisted and I’m currently postpartum, having had a c-section, so I don’t want anything on my scar. Initially, I bought a pack of size 12, which is my usual pre-pregnancy size. They have a lot of stretch, so I actually purchased another pack in size 10, which I prefer the fit of. The size 10’s are perfect - so perhaps size down. The size 12’s almost felt baggy as the day went on! The material is lovely and silky and the fit is perfectly high waisted. Totally converted me to large knickers - only thing you can’t get away from is a VPL, of course!

So good I had to repeat order

Originally posted on marksandspencer.mom (UK)

I have had several packs of these knickers previously, hence why I ordered again. Very comfortable, no visible panty line, lightweight and comfortable. I would have liked the colourway to include blue tones too but they don't seem to be available.

Best knickers ever!!! Super comfy. True to size. Don’t show VPLs under clothes. I have about 20 pairs. Please M and S, don’t discontinue these like you often do with the Body bras that fit me.

I always go for these as I find them really comfortable, just wish they did more colours in three set as opposed to mixed colours.

Not quite perfect anymore

Originally posted on marksandspencer.mom (UK)

Yes, I recommend this

I’ve been buying these sets of three in a size 12 for a quite a number of years now since they started doing them they have been the comfiest, no elastic that digs in the legs or waist and fit well under clothes but I’ve noticed this time the sizing is different, they aren’t as deep as my other pairs and gussets are measuring narrower which isn’t ideal for period and hygiene products. M&S stop changing a product that was perfect you’ve done this with the flexi fit bra in the DD+ and ruined it don’t do that with the pants as well.

Comfortable, great fit. I’m actually between a 12 and 14, I buy 12 in M&S trousers but find these are perfect for me in a 14. Have been buying them for some years now!
