Very stretchy fabric

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Very, very stretchy that you could easily go down a couple of sizes and they would still fit – hard to tell which is the right and wrong side – you can only tell by the label

Poor fit

The high waist on these thongs is great but overall the fit is poor , they keep moving out of place which makes them uncomfortable

Wouldn’t Recommend

I purchased these for every day wear. I ordered size 20, two sizes smaller than my trouser size and they fitted really well and were comfortable to wear all day and night. I like the flexifit range as they are lightweight and soft to the touch. However, by the morning they were really baggy and did not fit at all, they gaped around my buttocks and at the front by the legs. Will not be ordering again, even in a different size as i do not want to waste my money. Such a shame as i really like these.

Great fabric, very comfy fit, my only issue is if you need to use any pant liners they don’t stick to the fabric

Awful, will never buy again

Originally posted on marksandspencer.com (UK)

Really disappointed. Been buying this style from M&S for a long time now but I’ve noticed the quality slowly deteriorating. This time the gusset was completely unstitched in every pair in the pack, holes everywhere before I’d even worn them. Ts&Cs state that you cannot return underwear and I’ve had no luck getting hold of anyone from customer services to complain. I won’t be wasting my money buying anything from here again, standards have slipped massively, they’re just another fast fashion company now.

Runs small and keeps rolling down! I sized up after reading other reviews but wonder if this is the reason it keeps rolling down.

Excellent underwear garment, especially for summer clothing. Great product in that it is perfect sizing and no visible seams.

Cut of material badly fitted

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Material is a nice flexible fit around waist, however far too small in cotton material area and very uncomfortable. Will not wear again

Found the material to be a bit thin for M&S so retuned. I’m usually very happy with their stuff but it wasn’t quite what I was looking for

Material

No, I don't recommend this

Bought for the no vpl on the basis the gusset was 100% cotton , they didn’t feel like it was when on, maybe they but wore them to gym once and ended up with a UTI so they are gone. I’ll stick to 100% cotton now regardless of the vpl, not worth it

Good for menopausal bloated tums!

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

These are great as they are comfy and don’t show through clothes because of the colour. In addition they are great for those with a menopausal bloated tum, as they are higher waisted than the other ones sold. I now have all three colours. Highly recommended.

Really comfortable… wasn’t sure how they would be but, perfect, ideal if you like that ‘security’ of the high waist
