I just added this pattern to the Etsy shop, and I am surprised. It’s from 1980! When you think of the 80s, you probably think of huge shoulders and Dynasty-esque fashions. That is partially right, as those types of styles started showing up around 1984 or so, but the cusp of the 70s and 80s had some very soft, beautiful fashions. The most popular Gunne Sax patterns were from 1979-1981, so there was a lot of gorgeous stuff before it got all serious.
That being said, I would’ve put this one in the late sixties or early seventies. It has a Game of Thrones or Renaissance vibe to it because of that cape, and those weren’t seen commonly in the 80s. If you take the cape away, it’s a distinctly Victorian vibe as was common in that time period. That cape definitely IS the look. Make the dress in a deep color with metallic trim and it could be Mother of Dragons cosplay. Am I wrong? Maybe, but it’s a stunning combination nonetheless.
