Terrible quality and not as shown in the pictures.

What I got is NOT what is shown in the pictures. Have been buying the all black pack of these for years - the ones with the scalloped edge. But there is NO scalloped edge on these, and the texture of material is completely different. Not the nice plain cotton. Super disappointed and have basically been sold a different product. But we were going away so needs must.

Incredible quality, fit amazing. True to size, I love that they are pure cotton, that’s the reason I get them. Bought them multiple times.

Sized small

A little bit skimpy on material compared to others. Sized small too so maybe better order size bigger than usual.

Cheap fabric, poor fit

Originally posted on marksandspencer.com (UK)

Have had M&S pants for years. They are now thinner, cheap fabric and a lot smaller. Obviously have changed suppliers and not for then better. The fabric used to be a lot thicker and softer. Will start looking elsewhere from now on. These don’t fit like they used to and feel cheap.

Poor

Originally posted on marksandspencer.com (UK)

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

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

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.

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.

Terrible quality these days.

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.
