No as good as they used to be as others have said but still comfy! My day-to-day go-to undies!

Have so many of those thongs in black but noticed them in burgundy. Love them. Gorgeous colour, I love the fit. They don’t dig in. My daily staple. Please never stop making them.

Really disappointed

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

These really are too baggy. I ignored previous reviews saying they are too large but I wanted the fabric. They just don't stay in place. The gusset ends up to one side and the throng piece ends up crossing my bum cheek! The one star is the material is soft feeling.

Too narrow gusset

Nice fabric. Disappointed with the cut - think the gusset area is too narrow.

Big and baggy

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

I like the material, really soft, however they seem on the big side and seem to stretch with wear, going baggy in all the wrong places

Soft fabric, very comfy. Would say they come up slightly large but I prefer that as the elastic waistband doesn't dig in.

Not as they used to be

Originally posted on marksandspencer.com (UK)

I already had a pair of these from a couple of years ago but unfortunately the newer ones are thinner, stretch more, which doesn’t work well are are slightly larger than previous version, I was disappointed!

Great thongs, no vpl

Originally posted on marksandspencer.com (UK)

Wanted to try these as have the matching bra. They are so much more comfortable and fit a lot better than cotton thongs. They fit really well and look great under trousers and leggings - no obvious lines.
