This is a Chinese dress-style lingerie set with side and bust openings and lace, combining elegance and sexiness. The reason there is no size indication is likely because the sides can be adjusted with the included ties. This is an unused item that was opened for photography. Please check photos 2 onwards carefully before purchasing, as there may be changes in specifications compared to the first photo. It is actually whiter than in the first photo. Please understand that this is a pre-owned item that has been in the possession of an amateur before purchasing. 0205-10
