Comfortable, lightweight, smoothing
Lets start with what I was looking for, a lightweight high leg pair of undies to smooth my tummy under a skirt for an evening out, in the middle of a hot summer, where I would be eating. Did they deliver? 100% yes. Sizing, I followed the size chart and chose XL (size 20) and although when I unpacked them they looked a little small they fit perfectly and were very comfortable. Zero roll down, they stayed in place and were easy to replace when visiting the bathroom. The thong was comfortable and I found the overall quality to be good. Now, lets get honest for a min Ladies. No piece of elasticated fabric is going to turn a size 20 into a size 12! However, if you are looking for something Lightweight, fuss free, to give you that little bit of extra confidence and disguise those peskie tummy rolls I would recommend these. They performed the function I was expecting and the colour (Cafe Au Lait) worked well with no shine through under a white skirt. I paid ยฃ14.75 for these on offer and thought that was a fair price.

Not for tall people and not full briefs its a thong ( wasn't really clear)
First of all It wast really clear that it was a thing I was buying . So support for butt at all ( in fact it cuts it off and makes it stick out a bit more) Amd they ard not made for tall people. The waist band is approx 3 inches so doesn't really fix my problem but inhances in and out bits. If I get a size bigger they will be baggy at the crutch maybe I'll try and find full briefs somewhere but at that cost per pair I'll run out of money and no pants to wear !!

very stretchy material,not recommended
Very stretchy material. I took a size smaller. They don't squeeze the belly at all. I can't return them or swop. I DO NOT RECOMMEND!!!

Support on tummy area wasn't as good as expected so they have turned out to be an expensive pair of "normal" knickers.

Make sure you understand what youโre buying
Product not like the pictures. Too small and too brief.

Still a great seller, but watch the sizing.
This seller ships quickly and items do not take long at all to arrive. This item was exactly as described; however, I gained a few pounds and thought I'd order a large instead of my usual medium. There is a huge size difference. The large ends up looking like a super high cut 90s thong.
