Ratings & Reviews

Undie-tectable Thong is rated 4.0 out of 5 by 2.
Rated 5 out of 5 by from Totally invisible ! I had a wedding dress that was a nightmare to find underwear for as the material was not forgiving at all! I bought this on a whim and hoped they would be ok and they were perfect! No vpl or dodgy underwear showing, they were amazing and so comfy- thank you

Rated 3 out of 5 by from Uncomfortable They definitely flatten any tummy bumps, but I found them really uncomfortable and had to return.
