Technically though, since this fabric was bought several years back, it probably is more like 2016 does 1970's does 1940's...at any rate...I pulled out another 1940's pattern I had yet to test, a hunk of fall-color-schemed material and went to work.
The only other "alteration" (other than a pattern piece I had to draft) was to narrow the sleeve seams from .5" to .25".
About that pattern piece though:
It was a really simple dress to put together, the most complicated part being the waist inserts...I basted them before top-stitching. Next time, I think I will try to make sure front and back insets match up a little better...but I let it go with this time since it's very busy print.
I think the neck ruffle was a bit of a flop, so I ended up doing some folding and tacking to make it look better (and make it stand up).
