Classic French jacket in a darker blue shade, in a good worn condition but with paint and glue specks on the front, the sleeves and the back.
Medium size, 22.5" pit to pit, a good medium size. Soft worn cotton.
4 front buttons, small collar, 3 patch pockets.
Most likely 1950s, although specks may be from a later date. Nice inner pocket with a different type of cotton fabric.
