I miss understood the shipping date ... oops! Hope I don't get into trouble, but it's not bad having a sneak peak ... right?
It's always hard to know what the Simplicity customer wants ... authenticity or easy construction.
The silhouette for this period is high waisted, but that doesn't mean the dresses were unboned and ladies were going without corsets. These drapey dresses were mounted on inner bodices that had boning that extended a couple inches below the natural waist, which allowed the back of the waistline to be set higher than the front.
Evening dresses from this period frequently had outer bodices that were artfully draped over a tight form fitting boned foundation bodice.
Back to 1913 ... It was so hard to find out how these dresses were constructed. Janet Arnold has a pattern from the period and I am always grateful to the illustrations in "Costume in Detail" by Nancy Bradfield. But, for sewing, I looked in magazines, pattern catalogs and even sewing books from the period and nothing was said about the boned inner bodice I knew should be there until I found a scanned ebook at the Google Books site. "The American System of Dressmaking" by Miss Pearl Merwin, published by The American College of Dressmaking in 1909 and copyright in 1912, finally had some information about this. They have a small paragraph saying to mount the dress onto the foundation bodice. I think at that time, this was the standard way to construct a formal gown. OF COURSE ... everyone knew that!
Below I will show you some of the images I used for my 3 dress designs.
There is a very nice blog post about fashions from this period at the "Making Changes in Life, Health, Crafting and Sewing" blog (long name!). I recommend it.
