This Christian Dior dress is made of silk and wool. It has a lovely subtle sheen to it. This is a size 6 but fits more like a 4. I believe the dress is vintage based on the small fit of the size 6, but am not sure. It is fully lined (with silk). There are multiple hook fasteners for a seamless fit, as well as a button that fits into an inconspicuous loop. The upper back portion remains slightly open as a slit. There is a minuscule stain on the lower portion of the dress (pictured in the last photo) and I only noticed it when I was carefully inspecting the dress for imperfections. This is in EUC and from and smoke and pet-free home.
