Best ever underwear

Yes, I recommend this

I’ve been buying these knickers for years. I am allergic to what I call old fashioned knickers, where the actual elastic can come into contact with your skin! So when these came onto the market, they saved me from severely sore groin areas. Being allergic to rubber sounds quite silly, but believe me it’s a thing. So when these knickers came on the market….. I was a very happy Flexifit advocate. Thank you M&S, best knickers on the market. 😊

Disappointed this time

Originally posted on marksandspencer.ie

A little disappointed with this underwear. I have bought these several times over the last 10 years and there is always a slight change in the manufacture. However, this time there is less material in the leg cuff leaving them slightly skimpier on the bum. So not as happy as usual with this purchase and the photos online do not represent the reduction in material which has nearly halved.

Nice and stretchy and comfortable but panty liners won't stick to them so I won't buy them again.

Not what they used to be.

No, I don't recommend this

The white ones had poor seams with oil marks and damaged fabric. I had to return them. The black and beige ones ride up as leg holes are too big. Poor quality for the price. Bring back uk manufacturing.
