Ok - but bikinis are growing again

Yes, I recommend this

I've been wearing these for years. Over the last decade or so, the shape of the pure cotton bikini knickers has changed a lot. They are wider at the sides than once they were, and also cut a bit deeper round the undercarriage. This year's model is even deeper everywhere, meaning that they are moving more towards a "high leg/shorts style" cross cut that works a lot less well for me than the slighter sides and lower overall cut used to. The old ones tucked neatly under the tummy flubber: these crease and fold here and there and are more likely to chafe. (Sorry, possibly TMI, but that's how it is!) The fabric itself is also thinner and I don't get the impression that they will last too long. On the other hand, the pure cotton is a life saver to those of us who react badly to lycra, and there are 3 colours to choose from this year instead of just black which was all I could order last time. It would be lovely to have something nearer to the old cut, and ideally in some more interesting printed patterns rather than just black, white or beige and one sold-out-before-i-got-there print, if that's at all possible in the future!

Very poor quality

No, I don't recommend this

A case of charging more for poorer quality. So thin they are almost see through. Rubbish, will not be buying again.

M&S Simplicity

Yes, I recommend this

Bought this pack of black cotton underwear to mainly use for work. They are comfortable and a good fit. A straightfoward buy, as M&S always comes up trumps for quality and price.

I've been wearing M&S knickers for as long as I can remember and bought these to replace my old one, which were getting past their best.

Okay

No, I don't recommend this

Run small and don’t wash too great but kind of to be expected if they’re made from black cotton

Quality Getting Worse and Worse

No, I don't recommend this

I’ve bought M&S knickers for over 20 years now and it’s so disappointing that the quality has gone so downhill. These are the worst knickers I’ve purchased. Poor quality and the material feels super cheap. Not as stretchy and comfortable as they used to be. I’ll be shopping elsewhere from now on.

Nice and soft

Yes, I recommend this

As a slim 60 year old i now need comfy pants but dont want to wear full briefs yet. Thought i would try these. The cotton is very soft and they are not too skimpy. I went up 2 sizes for comfort.

Not what they used to be

No, I don't recommend this

The quality has fallen so much. Thin fabric and strange sizing. I’ve purchased these for years but will be looking elsewhere from now on.

Quality is good but size isn’t …

They are not properly sized, regardless of having bought different pair in the same size, these ones are too tight

Yes, I recommend this

These are well made under-garments, comfortable to wear for everyday use. Cotton underwear is always best!
