This post is about Jyn's blouse. I use the term blouse as the article seems to fit loose under the bust (based on the cast photo),at the waist and in the sleeves. The ease at the waist and sleeves is based on the posterior photo of Jyn running in the “transportation center” (ID 612234). In this photo it appears she is wearing the blouse and the vest but not the jacket. This photo would also indicate the fabric drapes and moves freely. Others in the build thread are basing their design on knit fabrics and Butterick 6132. This pattern for knits is termed “close-fitting” so cutting the pattern a size or two larger may be the “easiest” way to obtain the desired ease. (I am starting with size 14, View B for a size 10 individual.)
EDIT The fabric was later determined to be woven not knit so there are probably better patterns to use as a base. I have undated my patterns twice based on newer information.
There has also been discussion of how the front yoke pieces might be formed. My take is there is a left and a right front yoke panel which can be made from the pattern's original part #5 (Yoke Front B). Instead of the a single bottom yoke edge extending from armscye to armscye, each panel goes from the armscye to a point about one and one-half inches beyond the front centerline. To modify the pattern,I am extending the straight line at the bottom and also adding a straight line out from the neckline at the center front. (This adds a 1.5 inch wide rectangle to the edge where the pattern had a foldline). Just as the original instructions call for cutting two yokes, I envision cutting two left and two right yokes. With right-sides of the two yoke parts together (one left yoke and one right yoke), the neckline and the edge of the new extension can be sewn, trimmed, and turned. This will then show the right side of the fabric when the point of the yoke extension rolls forward. When assembled, the left yoke lies atop the right and the lower edge of both are sewn to the lower front panel part #6 (Front B). This combination forms the entire blouse front. The top edges of the yokes wrap around and rises up above the natural neckline in what is sometimes called a“stovepipe” neckline. This is shown in the trailer at about 0:15 seconds (I have not seen a good screen capture which shows this detail). To obtain the stovepipe rise will require an alteration of the neckline on both the yoke and back pattern pieces.
As I start to modify and test my pattern I am interested in other opinions on my speculations.
