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.

Just what I expected!

Yes, I recommend this

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.

Pants okay

Yes, I recommend this

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.

Very disappointed

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!

Buyer beware - reduced cut= period pads won’t fit

No, I don't recommend this

These are a buyer beware, with such a decrease in quality from previous years that I am switching to Sainsbury’s or anywhere else I can find 100% cotton. The waistband sits tight with the changed elastic to plain, the crotch and gusset are so thin new that a regular pants liner / or pad has to be very carefully placed because the pants liner is wider than the material for the underwear itself. M&S are cutting fabric quality and the actual cut of these pants to as fine a line as they can. ‘marginal gains’ per meter fabric used to increases profit but it makes for really rubbish unusable underwear. I would rather pay more for the style to return to what it was.

Ok

No, I don't recommend this

Hi bought the knickers in rose quartz colour to wear under pale or see-through light clothing I thought the colour would be like nude same as a skin tone but the colour of the pants is too dark and so they still show up through pale or see-through clothing so I’m very disappointed the colour of the pants needs to be 50% paler because even white pants sometimes really stand out if you’re wearing like pale blue or pale pink clothing

Not good quality but good value

I am disappointed with the pants even though they are good value for a pack of 5 the quality is really not good. I purchased 1 pack that shrunk in the wash so then I purchased another pack in a bigger size to allow for wash shrinkage. The new pack has 1 pair with damage to the seam where the elastic has split/torn.

Hospital knickers

No, I don't recommend this

Horrible, like something you’d be given in hospital. I’ve purchased the cotton knicker range for years and they are by far the worst.
