A coat upon a coat
I still want the front and side panels lined in a second layer of melton. It'll create a second layer of air for warmth and if I reduce the gsm of the fabric, it should do it without weight. My pattern cutter calls it a coat upon a coat and I can tell she's dubious.
I need to see the idea through and if it doesn't work, I'll chalk it up to a lesson learned. I'm going to drop the melton layer off the back panel and replace that with a silk lining. I think that'll help with the drape and with getting it on and off.
