All measurements are taking laying flat. Vintage sizing is unpredictable and can be misleading so I left the vintage size out of the listings and instead include critical measurements. Most vintage skirts and pants are meant to be worn high on the natural waist.
Waist 14-18" (elastic), rise is 13" and hips are 20" (no stretch) inseam is 26"
These are labeled a medium and I think they probably fit anywhere from a 4-8 best. Shown on size small dress form
