In chatting at a local history program, a friend seemed disappointed to learn that i don't have any 1920s patterns in stock right now. Turns out she's looking for something to use for uniforms for domestics, something that would be appropriate to the 1918-1922 period they want to portray at Morven Park. Never one to pass up an interesting research challenge, i said i'd look into it a bit and see what leads i could send her.
(That 1927 dressmaking book i just got is looking better all the time... and i've got another one inbound that was printed in 1922, but to judge from the plates, the content is from the teens; pictures when it arrives, i promise)
A lot of the photos online have little or no accompanying info (date, location, rights...), and so aren't the sort of thing you want to steer people to, but gave me a bit of an idea what reproduction and period patterns i could recommend. I'm pretty comfortable up through the late 19th century, but haven't done much 20th - this was fun. And who knows, maybe it'll turn into another project.
