    Love the thong

    Sieve thongs fit so well, they dont dig in on my sides like smaller banded thongs do. TTS

    Super comfy and invisible under clothes!

    This is a remarkably comfortable thong that’s surprisingly breathable — so it’s super versatile for working out or just vanishing seamlessly under dress pants.
