They fit great but my daughter says they lace around the edge so couldn’t wear with a fitted outfit

Extremely brief

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

Bought these to wear under riding tights to avoid the dreaded VPL and picked these as I prefer natural cotton underwear. Although I am size 12, unfortunately they are extremely brief to the point of hardly being there at all. Indeed, the gusset is so narrow it provides minimal front coverage with a good 1cm missing either side and I couldn't have risked wearing them for riding or any sporting activity.

Very comfortable and breathable, would definitely recommend if you have eczema during summer as they don't rub.

To be honest I bought them for my daughter who is away at the moment but I know she will love them as she has had them before and won’t wear anything else

These thongs are totally as I expect from M&S underwear. Good quality, lovely fit, soft feel cotton, AND in pretty colours and print.

I know its a cliche, but M & S knickers are always the best for fit and value

Great value cotton knickers for workouts

Originally posted on marksandspencer.com (UK)

Great knickers for under my workout leggings. Always size up a couple of sizes though, in all knickers! Always comfortable and last longer IMO.

Had some of these already and decided to buy more. Super fit, exactly as expected. So soft that you forget you're wearing them. Wash well.

Panties our underwear

No, I don't recommend this

Panties or underwear , I had high hopes for this 5 pack, but unfortunately they didn’t meet my expectations. The fabric feels loose even I got the right size, and uncomfortable against the skin. I prefer the other one I got few months ago. Much better.

Nice as they are cotton but size up

Originally posted on marksandspencer.com (UK)

Nice but don't cover too much skin, are quite skimpy and maybe size up. Could cover a bit more of the front!

Sized up and glad I did. Bring cotton, they shrunk on the first wash. Otherwise, does the job!

Nice material, sizing is on the small side.

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

Nice, natural material - which is always preferable over synthetic materials - however I ordered a size 14 (I'm a 12/14) and these are definitely on the smaller side I find!

Quality is average

These are fine, but quite thin material, borderline see through. I wouldn’t be buying again.
