Butterick 8809 Bubble-Back Overblouse / ca.1959 and does this look like the perfect bowling night blouse? A tight pair of capri pants and there you go! Then off to the malt shop for a root beer float. Okay guys that's even out of my era LOL - but not by much.
It was a toss-up between this pattern and Butterick 6906 Slinky Top, Jacket, Wrap Skirt & Pants 1970's which I'm lucky to have in several sizes. That era of Butterick had the most colorful illustrations.
Realized I was quite low on Stretch & Sew Patterns so dug in the wonder closet (it's kind of like Harpo Marx' bag that he keeps pulling the most outrageous things out of from pianos to dog sled with dogs) and found some which went in today.
