100% Silk. Color fading on the front, as seen in the third photo. The back is in near-perfect condition, which is a shame. It might not be noticeable in dim lighting. The sleeves are made of silk chiffon and are quite flared. I was considering discarding it, but it's lovely, so I'm hoping someone can find a way to wear it. I'm selling it at a low price.
