Great but size down

Very happy with style and neutral colour which matches the flexifit bra but wish I'd sized down as they come up big

One size does not fit all!

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Having previously purchased the same make / fabric /size but in the period pants I assumed I would buy the same everyday knicker in the same size. How disappointed I was to find they fell down around my feet, not a good look in public.

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.

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

Originally posted on marksandspencer.com (UK)

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

Originally posted on marksandspencer.com (UK)

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

Originally posted on marksandspencer.com (UK)

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.

There's not really much you can say about an item that is necessary. They are comfortable and the colours are nice.

Preferred the original design

Originally posted on marksandspencer.com (UK)

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.
