    A perfect match

    I bought this thong to match my sieve bra in slate. The color is dreamy and the material is super comfy and breathable. I’m usually a size small in high waisted underwear but purchased this in a medium since in sits so low on the hips. Super sexy!

    Love love love

    This underwear is so high quality. You can tell from how it feels. The mesh is stronger than you would expect. I had a fear it would break but that doesn’t seem to be the case at all. Worth the purchase
