Vintage Tapestry Blue & White Polka Dot Blouse

This is a beautiful vintage button-down blouse handed down from my grandmother-in-law. In excellent vintage condition. Baby blue with white polka dots, metal buttons, boxy cut w/angled sleeves, shoulder pleating, curved hem, slightly longer hem in back. Lightweight material, most likely cotton (no materials or care tag). RN# 56110. Approximate Measurements: pit-to-pit 23in, shoulder-to-bottom-hem 22in For reference, I am usually a medium in most blouses but this still fits oversized on me. I would say fits more like a large but please compare measurements to your own clothing to ensure the fit.
