Stylish and comfortable

Yes, I recommend this

Lovely underwear. Good stretch, lovely to wear and smooth under clothes. They wash well and tumble dry. I go down a size from my usual 14 to size 12 as they are a generous fit.

Fabulous pants.

Yes, I recommend this

Always buy these pants. Really comfortable, like the higher waist as you don’t get a line when wearing dresses.

Typical M&S lowering quality and standards

I've been buying this style for years but the latest pack unfortunately are noticeable lower quality. Beware, the quality has gone down so much they do not last as long as they used to. The newer versions go threadbare/see through and lose shape after not many washes at all. This pack will hopefully see me through just long enough to source some good quality knickers elsewhere. I will not be rebuying from here as the quality of all the women's basics it seems have lowered far below what I am willing to accept from M&S. Do better.

Good moisture wicking panties

Yes, I recommend this

I have multiple pairs if these knickers. Having lichen sclerosis and in need of moisture wicking undies these are excellent. The fabric is so soft it is just like silk. My only gripe is that the cotton insert could be somewhat longer.

Comfortable pants

Yes, I recommend this

These pants are comfortable and soft. I like that the don't have any rubbing seams and they also dry quickly. They come up slightly large on me though, particularly around the top of the leg where they feel a bit baggy. I'd prefer them to be snugger there. I'd buy them again, but will try a size down.

Preferred the original design

I bought this style of briefs in black when they first came out, and the side panels were a lovely silky fabric. Am disappointed that the panels are now made of the same fabric as the main body. However they are a great fit and I love the colours.

Good replacement

Yes, I recommend this

Always comfortable and I choose these briefs now as the ones I used to purchase have been discontinued. I always think it is a shame when good items are discontinued at times, but overall these are an acceptable replacement. I am a size 14 and they are true to size.

Love these

Originally posted on marksandspencer.ie

Yes, I recommend this

This is my 2nd order of these. Found them and was delighted with them and then the online shop went offline & could never get my size when I visited in store. Delighted to get these in more colours now. They don't cut in at the leg are high rise enough to cover my middle age / had lots of kids tummy and the fabric is so soft. Highly recommend anything in the flexifit range and these in particular.

Very comfortable- second skin

Originally posted on marksandspencer.ie

Very soft and comfortable and do not rise up, however after 1 wash they have stretched massively and now roll down/don't stay up. Very annoying. Would recommend sizing down for this reason, but unsure if this would still be an issue.
