Great Cotton Knickers...

Yes, I recommend this

Nice cotton knickers... it is so hard to find proper knickers these days and especially 100% cotton.. There are so many pretty ones but sadly 95% of them are either thongs or Brazilian.. which are both so uncomfortable... whatever happened to pretty bikini/mini briefs... These are good everyday wear but they do fade quite quickly... They come up small so even though I am only a 12 in bottoms, I went for 16 size so that the elastic does not dig in..

Thinner material than in the past

No, I don't recommend this

A little disappointed with these. I've been buying them for a few years now and my older ones are a much thicker more substantial material than the latest version. Needless to say this cheapening of the quality is not reflected in the price.

Not high quality

No, I don't recommend this

I wear an 8 or 10 clothes, I have to buy 12 in these knickers - the shape is not entirely right for me but I want pure cotton and this is all you offer. They also shrink in the wash (30C). You used to make quality pure cotton. Rather than changing all your other product lines perpetually, put some money into creating a good quality product and people will continue to buy it.

Comfy, lightweight and 100% cotton!

Yes, I recommend this

These are really great, very comfortable, very well priced too and 100% cotton! I have allergies and had been spending a lot of money elsewhere on 100% cotton briefs, that were not only extortionately expensive, were thick and uncomfortable to wear. These are lightweight and super comfy. I sized up and they fit lovely. Highly recommend esp if you have allergies. The other colour packs are great too!

Ok

No, I don't recommend this

Quick delivery. Quality of the knickers isn’t the same as they used to be and the elastic isn’t as stretchy either.

OK, not great - need to size up

No, I don't recommend this

These don’t feel as good as they do usually and they are definitely smaller than usual.

Not great

No, I don't recommend this

They’re cotton and black, so a star for each of those. Other than that, poor quality thin material.

Awful!

No, I don't recommend this

Thought i'd give these another try but they are just awful. Really thin and no structure to the elasticated part.

Trim Has Changed

No, I don't recommend this

Love M&S cotton pants and have been buying this style forever but was disappointed to find you have changed the style of the trim, the new style is not as nice comfort wise or look.
