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 …

Originally posted on marksandspencer.com (UK)

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

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

Poor quality- drop in M&S standards

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

These 5 packs of underwear from M&S are a staple and I have bought them for decades in different colours. Sadly the past few years I’ve seen a noticeable drop in quality- fabric with thin and elastic is uneven- the garment falls apart in a few months. M&S once again have lost sight of who their core customers are and what we value.

Need to go up a size.

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I have been buying these pants for quite a few years, as other people have stated the quality of the cotton has become thinner ,I still find them comfortable, but I am a size 12 and I have to buy a size 14, they used to be true to size, but the past two times I’ve bought them. I’ve had to go up to size 14 and I’m not a size 14.

True to size. Washes well. Material quite thin and see-through compared to previously. However, still my favourite underwear as it looks great even after several washes.

Good quality bikini, good value for money. Real cotton, I would like these to come in many plain colours, not just black or white.

Poor and disappointing

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

I brought these, same size about a year ago. They were soft, stretchy and comfortable. Unfortunately, I recently brought them again. This time, the material is hard, has no stretch, uncomfortable and don't fit the same as before. Got them on-line, but that shouldn't make a difference.
