Vintage 80s 90s Jeffrey Dara Smocked Wide Leg Black Floral Romper Jumpsuit 12

Vintage 80s Jeffrey & Dara Linda Hutley Smocked Pleated Wide Leg Black Floral Romper Jumpsuit 12 Great condition, no flaws or notable wear. Bodice is kind of quilted or smocked, there is stitching throughout that give it a kind of crinkle texture. Included model photo of a similar jumpsuit in black to show example of style/fit. Size 12 on tag, I'm a 14/16 or XL and this is too small on me--I can get it on but cannot zip it. I'd say this is a large or maybe a medium, but please examine measurements in photos and compare with something you own to ensure fit.
