Two buttons missing in back-- I would take one from the bottom and one from the top and use a jeweled button for the top and sew up the bottom so the missing button doesn't show. About three small pin hole size holes in the delicate fabric of the bodice. Two of the buttons have fallen off, as you can see in the picture, but I have them and will either put them on, or send them with the dress. I have also purchased four plastic buttons that will blend well with the others, and which I will include with the dress if requested.
The 27" waist could be enlarged using the fabric from the incredibly long train. This dress is shown on my size 4 and the bust measures 18" from underarm seam to underarm seam. No label. Rayon fabric is a best guess. Iconic later 40's styling.
