Nicest knickers

These are so nice , lovely feel , great quality, very comfortable, great fit , no distortion after washing a wearing . I’d been hoodwinked by a brand online and gone with them originally for new designs but within a month had become distorted in shape and little holes BUT not M&S knickers.

Comfiest pants I have ever worn. Barely there in terms of awareness of their existence under your clothes but very much there in terms of coverage. Perfect pants.

The best for comfort.

I have never damage and can’t bare pressure on my buttocks and groin. These are buttery soft. And no nipping anywhere. I’d love them in as many colours as possible to match my many bras. I ha a high stoma so love that they cover it without a garment that’s medical in nature

Poor quality

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Fabric is not as good quality as previous purchases, also the cut is skimpier on the bottom. Don’t think I’ll be buying again.

Perfect pants

These pants were perfectly soft and comfortable in every way after recent abdominal surgery. They don't dig in on the waist and keep your dignity, you just don't know that you're wearing them. Great for wearing through the night too.

These are true to size, nice fabric and don’t show. I’ve bought them before and worn them out so these are replacements and I think in an improved fabric.

Never thought I’d see the day when I like big knickers but the day has arrived. Love these. Super comfortable and I’ve bought all the colours

My Favourite Knickers!

Nice comfortable knickers but they do become loose during the day's wear. Still my favourite knickers though.

These are the first high high-rise that are flattering for higher-waisted trousers but still comfortable

Not comfortable

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Disappointingly these are not comfortable because they have a habit of rolling down and not staying in place. They also aren't a full brief, they don't cover your buttocks completely.

Best ever underwear

Originally posted on marksandspencer.com (UK)

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. 😊
