Poor

Unfortunately, the quality was poor and did not meet my expectations. It shed fluff quite badly from the first use, leaving fibres everywhere. I'm disappointed with the overall quality and would not purchase again.

Wouldn’t repurchase

I bought these as they were 100% cotton and thought they’d be a good replacement for some similar ones I bought a while ago that needed binned. However these were such a disappointment. I know there’s not much fabric to a thong anyway but these really do feel like they’ve been made with the bare minimum amount of fabric. They fit fine but definitely don’t feel as stretchy which gives a bit of a cheap feel.

Nothing like the photos

They are nothing like the photos, terrible quality, poor finish, the edges are just raw. Would never have ordered them if the photos actually showed what I would be sent.

Ok so probably me that’s the funny shape but I found them totally wrong, bits were long that should’ve been shorter bits were wide that should’ve been narrower bits were thin that should’ve been thicker I mean there’s hardly anything of them but I tried them on but to me they’re unwearable

Poor quality, completely see through. No give in the fabric. Small sizing. Won't be buying again.

I used to love M&S knickers - now they are pathetically thin and fall apart after a couple of washes - I have some knickers I bought years ago that are still alive. Nothing in the past few years lasted. I am giving up on buying underwear from M&S - so disappointing

I usually dont think twice about M&S product quality but today I saw one of the thongs is damaged. The elastic and the fabric is separating. A bit disappointing. The other 4 were fine.

Lovely Cotton, But Too Low Rise for Me

Originally posted on marksandspencer.com (UK)

Yes, I recommend this

I like the quality of the cotton and they feel soft and comfortable. However, they sit much lower on the waist than I expected, which wasn't the right fit for me.

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.
