I used a pattern for a loose button-up shirt as the base and then changed things, looking at a RTW blazer and also an unlined jacket for ideas. I think the center panel needs to be higher or narrower and the back needs to be more fitted. I definitely need to learn how to draft curved facings. I also couldn't quite figure out how to manage the hem to side facing the way it was done in a RTW blazer. I don't trust that my machine and I can make a usable button-hole, so I skipped that and used salvaged clasps instead. I rather like how they look. I didn't intend for the lapels to fold over, but once I tried it on, it looked better that way, so I tacked them down.
I hand-stitched the hem and facings to the lining. I strongly dislike hand-stitching, but couldn't think of another way to do it without sewing the lining to the front of the jacket. The lining looks wrinkly because I made it slightly larger than the jacket.
I don't know if the jacket looks retro-stylish or plain frumpy with the skirt.
