Beautiful Seafoam green Silk evening gown.  Handmade has metal zipper so one knows it is at least from the 1950's. Zipper works great.  The luxurious satin silk is in lovely  condition with no snags or stains. Bodice is lines with same color lining silk. I actually purchased this in a vintage clothes shop in the 1980's just  because I thought it is so pretty and I paid a pretty penny for it then.   I never wore it because it was always too small for me and had it packed away in a cedar chest all these years, after I hand washed it in Woollite  laundry soap. Which is what I recommend to do because of the beading. 
Here are the measurements 

Waist  26"

Bust 32"

Length from top of shoulder strap  55"
