This top is by Eclipse Seattle. Sz vintage 36
It is made of nylon material/lace
Has jeweled buttons down the front of it
Lace back needs pressed to lay flat, see photos.
Small tear at top button, see photos. Could be repaired by a good seamstress (which is not me).
This blouse has a slight aged tint to it, I know you can soak it in the right wash mixture and remove it.
