This dress brings back waves of late 80s early 90s nostalgia! Made by Plain Jane, the green cotton knit tee knit dress  has black random sized polka dots. It has a scoop neck front & back, spaghetti straps, is fitted thru the bodice & hips where it meets the gathered double skirt. Very awesome!
 
Pre-owned, used; in good condition with no noted flaws. I had to repair a seam but it's all good now :-)
 
Marked as size M- shown on my size 4 mannequin and it's tight on her. Actual dress measures--
Bust-32" around at the underarm seams, without stretching the knit
Dropped waist- 36"
Side seam length- 31"
