Antique blouse with embroidery along the collar and the sleeves. It's tagged as a (probably French) size 48 which comes down to a Dutch size 44. It fits tight in the waist and a little more loose around the buste, beautiful classic shape. Will post pictures of the blouse being worn here asap.
Measurements are as follows (measured flat):
buste - 56cm
waist - 44cm
shoulder to shoulder - 44 cm
