After receiving the Sieve String thong in coral, my ladyfriend remarked that it was such a minimal but perfect design for a woman's body.
I am pleased with that review, although I will need to re-order in Medium, as her hips are a little fuller than I had calculated. I look forward to presenting this slightly larger version.

At first I was skeptical if this is like any other thong and if the material is high quality and I must say I am pleased with what I received. Comfortable, there and yet “not there”.
