I would buy again

Yes, I recommend this

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.

Great quality

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.

Exactly what I was looking fot

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

Cotton knickers

No, I don't recommend this

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.

Great quality

Yes, I recommend this

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

Disappointed

No, I don't recommend this

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

No, I don't recommend this

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.

Bit thin

No, I don't recommend this

A bit thin, but good value. I’d say the gusset is a bit narrow, too.

Cotton pants, which are hard to find nowadays. Would like more colours. Not the best quality cotton, but better than nothing!! Much better quality years ago, with patterns as well.

Bring back the old knickers

Haven't worn then yet but hoping they'll last a little longer than the last few packs I've bought. M&S knickers used to last for ever, it seemed. Lately, seams open up and edging lace frays after several washes. I'd pay more for quality clothes.

These knickers are not the same size as the ones I was replacing and they are totally useless for me

The elastic in these pants has already gone. I am going to have to throw them in the bin!
