Abstract: A foldable, rectangular, protective lingerie case with internal coupleable and removable protuberances, that is resistant to pressure. The protective lingerie case is semiflexible, foldable and manufactured in fabrics or leathers with polypropylene reinforcement and foam layers on all four sides and on the upper lid. It stores, transports, protects and conserves the shape of lingerie, especially of brassieres, in closed and narrow spaces, ensuring that the initial shape of thermoformed brassieres is kept intact. The protective lingerie case safeguards the bra's function and use features by avoiding deformation of the stored garment and guaranteeing its durability and design.
