Cheap and Nasty Quality.

No, I don't recommend this

Throughout my adult life, I’ve always worn M&S cotton underwear, but they’re so thin now, cheap quality and a poor fit. Not all at comfortable.

Recommend . Always choose M&S for knickers are they are pure cotton and comfortable to wear. Wash well and can be tumble dried

Bought size 14 and they are the same size as a size 12. Cotton isn’t soft to feel.

I would buy again

Originally posted on marksandspencer.com (UK)

I bought these knickers as I needed to replace some well worn ones. They are well made and comfortable but I notice that the side seams are wider now than they used to be, bringing them a bit higher up on the body. Why this has been done I have no idea but hope that M&S don't continue to change them in this way otherwise you will not be able to call them bikini knickers. Overall, yes, I would buy them again.

These pants are fine but just a little too low for me as my body has changed since turning 70. I’m sure they would be absolutely fine for a younger person though. They’re pretty & comfortable otherwise.

No one else seems to make 100% cotton knickers. I don’t want 5% synthetics in my knickers. I don’t even want 0.5% synthetics. I don’t care if they don’t cling or look sleek.

Great value basic product. I was surprised not to be able to buy it in store, but the order and collect process worked perfectly. That’s really useful as we don’t have a local M&S clothing store

Having bought my knickers from M&S for all of my adult life, I find these disappointing. They are very thin, you can see your hand through them! The quality is much lower than I expected from M&S.

No flimsy knickers here! Well made, comfortable and like that they do them in a nude colour

Lovely briefs full cotton, for my skin brill. Wore them, comfortable and so on, only problem after 2-3 washes the briefs have grown. I am spending every afternoon taking them in, it’s a slow job as they need to be comfortable and I do not own a sewing machine anymore. The quality is there they just fall down

I’ve been buying M&S bikini knickers for many years and they have always been a great fit and excellent quality and value. I’m not sure what’s happened to the design in these as they are not the same as my earlier purchases. Very disappointed, why have they changed? If it’s not broken don’t try to fix it!!

Cheap fabric, poor fit

Have had M&S pants for years. They are now thinner, cheap fabric and a lot smaller. Obviously have changed suppliers and not for then better. The fabric used to be a lot thicker and softer. Will start looking elsewhere from now on. These don’t fit like they used to and feel cheap.

Straightforward, comfortable cotton knickers. Not too high on the hips but not skimpy either.
