Rawson black blouse

Vintage black blouse with beautiful scalloped crochet trim and crochet / ribbon detail on the sleeves. Has a slight puff sleeve / gathering at the top of the sleeves. Crewneck. Bought this secondhand on here a while ago and previous seller told me they purchased it from the brand Rawson but I’m not seeing any brand tags. Not sure if it is fully vintage or reworked vintage. Feels like a cotton material, on the thicker side and feels like high quality, but I don’t see a size tag. Would be great in casual or professional / office / workwear settings. Marked size D / NL 44, GB 18, F 46, I 50, E 46. I think this could work for a variety of sizes depending on the desired fit. I am a size medium and it has a loose relaxed fit so I’m marking this as a medium. Can add measurements upon request
