This is a MIKIHOUSE dress. The size is 100. The color is pink with white and pink stripes. The Usako-chan design is cute. I wore it a few times during one season as an outfit for going out after I bought it. There is a B stamp, but I didn't notice any particular scratches or stains when I bought it. There are no noticeable scratches or stains, but please understand that there is some wear and tear and that it has been stored at home. I think you can still wear it cutely (*^_^*)
