Wore this stunning dress for a photo shoot. It has been in my closet since. See The Union made label - vintage dresses I’m best guessing the 50s or 60s. There is no size but I was a size 2 when I wore this.

Approx measurements-
Chest laying flat 16.5
Waist laying flat 12.5
Length 42

There is one dark spot on the bottom as shown and a few small light grayish marks on the shoulder area as shown. The interior near the shoulder has some staining but doesn’t show to exterior

Beautiful dress.
