Vintage Long Sleeve Dark Blue Blouse

Here is a super cool vintage blouse from the 70s. Feels like all polyester. Dark blue fabric with bold white stitching throughout. Six button front. It's fairly thin, light weight, and slightly sheer. It's in excellent condition with tons of life left. Here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 18"

Sleeve 22"

Length 26"
