Super cute vintage blouse that has the buttons in the back. I am not sure what the fabric is, I am guessing it is some type of polyester. It is very light weight and NOT stretchy. It has a little bit of a texture to it as well and no shine.
no labels inside.
Most likely handmade by someone who knew how to sew.
This is a larger size, but like many tops from the 60s, the arm holes are smaller then what we are used to, and the neckline is high.

Excellent condition overall, but I did find an area that looks like it was repaired with some kind of fabric stabilizer or interfacing. It’s not visible because an area by a button that that gets covered up when the shirt is buttoned. See the last two pictures for details one shows where the repair and the other shows what it looks like when the blouse is on. you can’t see it. size L (10 - 12).
