Here it is! Please excuse the mirror photo and bad hair. I cut this dress out over a year ago and never made it up, but felt the urge to complete it last night. The pattern is basically Butterick 6582, a repro 'Mad Men' style from 1960, but I've modified it by dropping the neckline, and tapering and lengthening the skirt a little to give it a more 50s shape.
Here's the fabric. I have some left, it's a chartreuse atomic print cotton barkcloth.
I have already begun drafting a bolero pattern to go with it, it's going to be 50s style, black with the green fabric as a lining, which will be visible on the turn back cuffs and collar.
