The size tag has been cut off so please see above pictures for approximate measurements for both the jacket and also the dress. It looks to me like it would be possibly a size 6?? But not sure. The elastic around the bottom of the  jacket is twisted inside. I have tried and worked on getting it untwisted but had no success. So don't know if it would be possible to get it all straightened out or not. Otherwise, in good condition. Comes from smoke-free home.
