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

Great value cotton knickers for workouts

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

Fantastic

Yes, I recommend this

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

Originally posted on marksandspencer.ie

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

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

Size up !

Yes, I recommend this

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.

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!

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