Who can actually sew the one hour dress in one hour?
Well, nobody, but certainly in an afternoon you could get most of it done. This video discusses the wisdom of that timetable, as well as a little history of the pattern, the woman who developed it and her story, and some general sewing pattern history. The One Hour really does want a few inches of ease to let that bodice drape (it's worked really well in rayon for me, and because it's almost all straight seams, you're less like to run into issues of stretching on the bias).
And the original pamphlet is available for free. Yes, I said FREE. So stop paying for this sweetie!
