Vintage Colorful Arldon Lingerie Japanese Top Size L

Rare find! Vintage Japanese Arldon Lingerie top in size L. I don't know the exact decade that it's from, but likely mid-century. Not sure if it was ever worn/washed. It is in very good condition, though it may need pressing upon receipt.There is a small stain on the front and a few very small splashes/darker spots on the orange front strip where the clasps are, but they aren't very noticeable unless you are looking closely. Material is rayon. Unsure of the original price, but I am pricing this appropriately since it is a rare item, but also taking into account the small stain on the front. While originally intended as a pajama top, it could also be worn to a party, and no one would know! Please note I can't guarantee total accuracy of the color in the photos due to lighting differences, monitor/screen settings, and the camera's color reproduction.
