SISC item #2 is sewn! I really appreciate all of the input regarding the sleeves of the jacket. Thanks to everyone!!
Here is the finished product. I really like the way that it came out! It isn't like anything else in my wardrobe, which is fun. The pattern is Vogue 1099, a Badgley Mischka design. It is a very loose fitting jacket, with a standing collar, shaping in front with pleats and gathered short sleeves. The pattern includes a slightly gathered undercollar, which I did not make. I basted it in, and it just didn't make me happy. Otherwise I followed the pattern. The lining pattern is included, but does not include the pleats, rather forms a sort of princess seam with the facing piece. It looks nice, but I don't think it has quite as much ease as the jacket front. As is was, I actually sewed a size 10 without alteration. There is so much ease that an FBA wasn't necessary. The fit is fine in front, but over a more bulky top, the jacket is a bit snug in the back and sleeves. Obviously designed to be a spring jacket!
The fabrics are both from Hancock's. The shell is a cotton pique and the lining is polyester crepe. Both are soft and have a nice drape. The pique has enough body that I didn't interface the body of the jacket at all, just the facings. I wanted a soft, more casual look.
So, who's wondering what I did with the sleeve? In the end, I did the lining per Vogue's instructions - gathering stitches which I tied off. Both Audrey and Jane M have made this jacket and found the sleeves to have sufficient ease in this area that reinforcement wasn't required. It looks good that way, but it was a serious pain, so for the shell, I used clear elastic to gather/stabilize.
I generally sew on clear elastic with a zigzag, but I wanted to preserve the look of the lines of straight stitching, so I used a regular straight stitch. It was a little fussier to sew on, but I think it looks good. I initially thought of shirring/smocking with elastic thread in the bobbin, but I wanted to be able to better control the finished length and that isn't really possible. Then Trena reminded me that shirring elastic seems to have a pretty short lifespan, and I want this jacket to last!
I really thought that this would be a good jacket for my belly, and while it does fit over the belly, I think that it makes me look rather more triangular than I actually am. Fortunately, I only have a few more weeks before we can see how it looks without the belly!!
