Disappointed with quality of material

Originally posted on marksandspencer.com (UK)

No, I don't recommend this

The material is much thinner than the original thongs I bought several months ago. Quite disappointing.

Not the same dimensions as the original ones

Originally posted on marksandspencer.com (UK)

The sizing seems to have changed since the first time I bought these thongs. They were originally a good fit and extremely comfortable. Now the material feels more loose which other reviews commented on (suggesting to size down to compensate). I did so and found that the material at the front is not wide enough to cover the front bottom, so very uncomfortable. The larger size is so baggy they move around and become uncomfortable. So I’m now looking for other brands. The most positive thing about these thongs is that the elastic edging is as soft as the rest of the material so barely noticeable. If only they could go back to the original sizing!

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.
