White beaded and sequined shirt

The beading and sequined work on this shirt is phenomenal. I don't know the maker the only tag on it says 34 which I imagine is chest size. I did try it on and it fit me I wear a medium. There is no missing beads and I have looked all over it. You can see the work that went into this shirt. My grandmother said her friend made it for her sometime in the 60s but she is 104 and can't remember exactly which year. It has a zipper in the back and is a little lower in the back. It is from non-smoking
