This is a white cotton negligee I bought at a used clothing store in Koenji. The tag says "16". The sleeves are 3/4 length. The length is about 7cm above the ankles on a 166cm tall person. It has a lot of cute lace! It doesn't have a lining, so a petticoat is recommended. In the coming seasons, you can enjoy the colors by wearing a colored inner layer underneath!
