Vintage 1950's Silk Beaded Top

One of a kind piece, it was custom made, no tags. In excellent condition considering it's vintage. There is only 1 spot on the back, please refer to photos. Some slight yellowing on the lining. All the beading is intact. Please refer to photos for measurements. I'm guessing this piece is between a size 2 and 4. There are darts in the front, ideally more for a smaller breasted woman. There isn't much give in the silk. There are 4 snaps along the neckline and a zipper on the right side under the arm hole. It's been in storage for 20 years now, it needs to go out on a night on the town!
