Michelle (at OldPatterns.com) has a score of mint-condition 1920s patterns right now. Check out this one:
This one almost makes me think that perhaps airship hostessing started in the 1920s, rather than the art-deco 1930s. I love the determined asymmetricality (and the Modiglianish pattern illustration). I also think with great sympathy of all the women in the 1920s who had to wear stuff like this and who weren’t sylphlike gamines. That must have really, really sucked.
These patterns are definitely on the pricey side but they’re mint, practically Starlight mint, actually. (Maybe Michelle has been raiding some time capsules …) The 1920s are where I start to feel that sewing patterns are edging into Collectorsville and out of the range of “I’ll make this up next Saturday for a lark,” but the boundaries of your Collectorsville may vary. (I think that for some folks 1950s vintage clothing is now edging into Collectorsville — as I skip gaily towards my dotage, I start to realize that The Kids Today are now buying “vintage” that I wore in junior high school, and that the 1950s day dresses I took for granted as costing $7, tops, in the local Goodwill can and do now hit three figures. Speaking of 1980s “vintage” — dear children, floral rayon rompers are not improved by the passage of time. Take it from your Great-aunt Erin.)
I have one or two 1920s patterns I’m holding onto just because they’re so pretty to look at … like paper dolls. But I think if you want 1920s patterns, you might want to hunt them up now, because I have been given to understand that once the new Gatsby movie comes out in December, there will be a rush to flapperdom in fashion. (I hope there’s a rush to 1920s men’s fashions, too …)
