Fab vintage 1970s dress of French origin.
Very good condition. Abstract circle pattern. Unusual collar. Flattering fit and flare style with matching fabric belt. Nice thick jersey style material.
From the following measurements (taken when the dress was laid flat), I would say that size-wise it would best fit a present day UK 16:
Underarm to underarm: 23 inches
Across the waist: 20 and a 3/4 inches
Across the hips: 23 and a 3/4 inches
Length: 42 inches
