Brilliant. I immediately bought more!

Perfect for what I needed. I ended up getting a couple more, plus the tanga, and some bras. I've worn them all out to events, as well as for exercise and they're just perfect. I normally wear a size 16-18 and the chart suggested I order XL, they looked a bit big in the packet but when I tried them on they fit perfectly.

sizing guide wrong

Having used the sizing chart, it stated I need a size large. So that is what I ordered. When they arrived and I looked at them, they are way too big and I could have used a medium. I did not even have to try them on, the thing is now, I have spent £35 for something I cannot use as they do not allow returns. So,if you are a size 33 waist, do not get the large. I have only given it 3 stars as the material seems OK.

Best underwear ever!

Amazing fit, amazing tuck. Great quality make and material.
If you want a nice, tight, tuck, size down.
Glad I ordered 3 pairs and will definitely be ordering more, haven't found a more comfortable or flattering pair of knickers than these.
