Great quality & value, comfortable, will buy again

Yes, I recommend this

Great quality, soft fabric, very comfy & good price. Bought to replace my daughter’s well-worn undies & she loved these. And I love them because they can be tumble-dried! Bought one set to try, will be buying more.

Comfy Knickers

Yes, I recommend this

I’ve been wearing these for a while, they are soft, lightweight and comfortable. I would size down as they offer a lot of stretch. Also, my only issue is that the material is so thin, they wear quite quickly and I’ve accidentally pierced holes in some with my nails unintentionally.

Disappointed with quality of material

No, I don't recommend this

Not the same dimensions as the original ones

No, I don't recommend this

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.
