These sheer mesh thong panties are made from a stretch mesh fabric and have a small but soft cotton liner sewn in with a cute floral print decoration in the almost see through fabric. They're sexy and comfy to wear all day. The back isn't so thin to be annoying but also isn't so wide that it shows up under leggings. Wear low or high on the hip for a more elegant look. Purchased new, tags removed and washed... EUC From a pet and smoke free home. Please *bundle* item(s) before asking questions.
