Best ever

Yes, I recommend this

I have been buying these knickers for years. They are not the most sexy, but they are so comfortable and are good to wear under more tight fitting clothes as there are no lines of underwear to be seen. They fit snuggly and wash well.

Loose saggy, gusset

No, I don't recommend this

I found the fabric comfortable, good fit waist belly and hips, but the gusset and legs were saggy. Will not purchase again

Material and style different to early flex fit

Won’t buy these again they are made from completely different material from the original flex fit and they go baggy around the bottom once worn for a while

Unhappy

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

Unsure

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

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!

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

Yes, I recommend this

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

Yes, I recommend this

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.
