Antique early 1900s open-side bloomers. Made of a light, sheer 100% cotton fabric. In fantastic condition, they were pretty yellow when I received them (due to age) but they brightened up nicely after a soak. Still has some small spots of discoloration, and a small area of thin but fabric/pinhole on the middle front as well as some other small holes. Fits like a modern small/medium, see measurements below for best fit.
