Vintage Geometric thin sheer blouse/dress depending on who’s wearing it. size 12

Such a thin and light dress. Very MCM vibes. Bold red, black and white stripping. One tiny tag reads 46 , that’s a US size 12. I’m a small, and when I try this on it, fit like a little dress. It is sheer and very thin. Very breathable. Measurements pit to pit. 18.5 inches length 30 inches. #mcm #newwave #vintage #punk #80s #90s
