Pattern: Diagram XXX from The Cut of Women's Clothes, by Norah Waugh, used as a base.
Previous Use?: Yes. I have made this same jacket style using the same pattern before when I made the Brown Taffeta Casaquin. The sizing is the same as well (I have yet to draft out this pattern into a larger size).
Bicep: 13" Max
Back Width (between armhole seams): 12.5"
Hem: 37" at front, 40" at back (cut for bumroll).
I made this jacket using the same techniques and patterns as the Brown Taffeta Casaquin. For all those details, please visit the post linked.
The jacket is 100% cotton, dark blue, with a floral print called "Jacobean" by the maker (and printed on the selvage). The lining is 100% linen, white, medium weight. The stomacher is interfaced with linen canvas and lined with the same red linen as the petticoat, making it reversible. All the visible stitching is done by hand, including the full edge stitching, eyelets, and all the work on the cuffs.
The petticoat is red linen, medium weight, and hand-stitched at the hem.
