Sidan Hawaii Dress

Vintage Sidan Hawaii dress in purple and white. No fabric listed no size listed please check measurements carefully. I suspect this is a size small based on how it fits me and the yoke measurement. Flowers on the yoke are appliqué the rest are printed on the fabric. Square neckline with three fabric covered buttons at the yoke. 18" bust, 23.5" hip, 11" across the bottom of the yoke, 10" armhole depth, 11.5" depth on the bottom ruffle. Very good condition. Hawaiian print, mumu style
