Cotton knickers

Yes, I recommend this

Great to find pure cotton knickers again and in the bikini style. Well done Marks and Spencer for getting these back in stock I have bought these for years and they suit me well as I don’t like Lycra.

Big disappointment

No elastine content so fit and shape not very good. Much bigger than all the other size 14 bikini style ones.

Great basic cotton practical knickers

Yes, I recommend this

Basic, cotton, practical knickers. A slightly bigger size than their other bikini knickers which I personally like.

Knickers!

No, I don't recommend this

OK but darker than I had hoped for! Also thicker at the sides than M&S bikini pants normally are, but needed some tan knickers so have kept them!

Not that good

No, I don't recommend this

Needed to buy 2 packs urgently as I was unable to use our washing machine for over a week due to a blocked drain. These were delivered on time but were quite large and didn't stay up!!!!! Was that why they were sdvertised as "no VPL" I wonder? If I had to, I'd recommend buying a smaller size than usual but I won't be buying them again.

Not as good as the organic cotton last year

No, I don't recommend this

These are not as good as the organic cotton ones in 2024. I’ve had to go up a size and they sit slightly lower. Only reason purchased is they no longer have the organic cotton ones

Price ok, quality not what it was unfortunately

Yes, I recommend this

The pure cotton bikini knickers were discontinued several years ago, much to my disappointment. I was therefore thrilled to find them recently in your Culverhouse Cross store. Whilst the sizing and fit are still good/the same, I feel the quality/thickness of the cotton has deteriorated and/or become thinner. This is a shame. I hav nonetheless ordered more online because the price is ok and will stockpile these extra in case the pure cotton knickers are discontinued again without warning. I have purchased extra in white and also a pack of black and beige.

Disappointing

No, I don't recommend this

The gusset is far too small. Can't use with a pantyliner.

Great fit

Yes, I recommend this

Love these cotton bikini knickers, pretty but functional. Functional? They stay put and no itchy scratchy bits to irritate. One thing though, please make them in a nude colourway.

Frustrated with what should be basic

No, I don't recommend this

I went against negative reviews and bought these hoping they would be a like for like replacement for previous ones which are wearing out. Unfortunately I was disappointed. Quality has gone down, they were also much smaller, and the seam is now thick so more visible under clothing. I just want comfy everyday underwear that's not ridiculously high waist and won't be obvious under an outfit - where can I find it??

Droopy drawers

No, I don't recommend this

I’m not sure what’s happened to M & S knickers, but these are decidedly droopy drawers. Thin fabric and the elastic is too loose. Disappointing.
