Sheer Mesh Unlined Novelty Thong Panties in a One Size fits most. I would say based on how much stretch they will fit well from XS to Sm/Med depending on how snug and revealing you want them to be. They are sexy and playful with absolutely no lining through the gusset and have an oily/shine/sheen to them. They are novelty panties but made to a decent quality. The fabric is smooth and soft and the elastic is nice. They have a very silky feeling and will be super cute and sexy! Purchased new, never worn or washed... NWT From a pet and smoke free home.
