80s abstract print mini dress, subtle puff sleeve

Adorable vintage dress (likely from the 80’s) with a fabulous print (see detail photo). No labels. Unlined but opaque. Material is likely synthetic: Has a poly (maybe rayon?) feel to it. I’ve cared for the dress by washing on the hand-wash cycle and laying flat to dry. The material is wrinkle-resistant. Measurements: Waist: 26-27 inches Length: 29.5” Armpit to armpit (laying flat): 17” Fits a modern size XS, size 2ish For reference, my measurements are 33” bust, 27” waist, 38” hips
