Not as Good as They Used to Be!

Poor quality cotton compared to what they used to be for sure. Not sure that I would buy again. Comfy to wear in bed or with joggers. I would not wear them as day to day pants due to the VPL

Disappointing....

No, I don't recommend this

Unfortunately these are not the same quality as they used to be. Very thin and flimsy. Have always loved M & S underwear but disappointed with the quality now.

Doesn’t fit to size

Too small for me. I’ve been wearing size 12 for over 10 years and still wear size 12 from other brands but this was too small. Advice is order next size up. And because I had opened and tried one on I couldn’t return so I had to get rid of the whole pack which was a shame.

Poor quality

No, I don't recommend this

These were poor quality and the elastic frayed on 2 pairs after the first wash. I have bought these in the past and they were excellent quality but sadly not this batch. Will go elsewhere next time.

What have you done to my go-to comfy knickers?!

No, I don't recommend this

Quality has been significant downgraded since I last bought a multipack of cotton knickers. Fabric feels thinner and the elastic has been reduced to the absolute minimum. Sizing has also changed - if you compare with previous M&S sizes you need to size up which is definitely not good for the ego! I appreciate that these have been cost engineered to hit a price point but I will not be buying these again!

Comfortable

Yes, I recommend this

Good product. The only negative is the trim doesn't sit flat sometimes so can be seen a bit more than normal under trousers. I sized up and they fit ok. Glad I didnt get my usual size

Good quality as always

Yes, I recommend this

I always buy my pants from M&S because the quality is always of a high standard. I would always recommend M&S for quality underwear in a variety of styles.

Gentle feel

No, I don't recommend this

These were comfortable at first but I felt that if I’d gone for a long walk, they might have slipped down a bit which would have been very uncomfortable. It might be that I should try a different style.

Ok

No, I don't recommend this

I’m not sure if I ordered the wrong ones but these aren’t like my previous ones. It’s a cotton material rather than the soft slinky material. They seemed to shrink a bit on the wash.

Not the same underwear.

No, I don't recommend this

I gave these 3* as I often buy M&S bikini briefs multi packs, unfortunately this time, they didn’t fit, they kept slipping down, they looked cheaply made and the elastic around the waist was very thin, I am a little disappointed on this occasion, as they are my go to underwear.
