I helped a client buy some beautiful party dresses recently, we also had to make sure she had the right undergarments which can be really tough with some thin jersey or silk dresses. This thong is magic, it both disappears under the clothes, and is comfortable. That would make it the holy grail of lingerie I think -
They are definitely worth checking out. And the line also includes boy shorts and strapless bras, all great things to have in party season.
