    Gorgeous!

    I love all things Negative! This is a heavenly color and the mesh breathes. I sized up in this style so the hip elastic is not so snug. I prefer smooth lines under my clothing. Usually I wear a L but for this style the xl is better.

    Very comfortable.

    These are very comfortable! The mesh breathes. I did size up so the elastic band doesn’t dig and create a line under clothing. Typically in the string thong I wear a L but I prefer the XL in this style.
