It is a lovely jacket. I also recommend the longer length. I would also encourage you to try and make the batting or other filler as thin as possible, maybe flanelette. That helps with drapability and is more flattering to those of us with more mature figures.
I remember taking my then early teen daughter to a big quilt show with me in Lancaster, PA. She kept rolling her eyes everytime we saw a lady in a quilted jacket. Her words were, " Mom, those puffy jackets don't look good on "ladies".
I will admit that I agreed with her that many of the real woman who were not size 6 or lower did not look their best in a bulky quilted jacket.
