This is a Marco Lumiere Waist Control Camisole. The size is S. Although it is new and unused, it is a used item being sold in accordance with Mercari guidelines. Shapewear can be sold as used items. It has been home-cleaned with Marco's special lingerie cleansing agent. Please understand that this is a personal inspection, so there may be oversights. I do not know the purchase date, usage period, or frequency of use, but it is in relatively good condition. This is based on the current condition, so please refrain from purchasing if you are sensitive to such things.
