The tricky part of the Sewing Circle question was finding the pattern, and I didn't have an easy time, either. I ended up using a vintage pattern from my mom's collection, Simplicity 6876.
It wasn't perfect (very slim 60's sleeves, had to change a few things...) but I was able to make it double-breasted and not put in the front darts, so it has more of the boxy shape of the original--just the side bust darts.
The other tricky part for me was finding the right fabric!!!! I've never seen such a cool wide stripe at any fabric store I've been to, so I went online. I found a place called Premier Prints, Inc.--they print their own designs onto 7 oz. cotton canvas, so have basically any cool print you've wished for, in lots of colors.
I wasn't sure what the 7 oz. fabric was like (suitable for clothing? Just home dec? I didn't know!) but Meg at Premier Prints graciously sent me some to try out and show you all. And I gotta say, it worked just great for this jacket!
Buttoned all the way up...
Back view, a little shapeless, thanks, 60's pattern...
And (cutest, I think...?) unbuttoned.
Proud of myself for branching out and doing a little tailoring-ey work. I gave it a full lining of a lightweight white, and of course also gave it the facing on the front, which I also cut wider for the double breasting.
The fabric is super fun, although I think the original may have been more coat-like and water resistant? This one's not, but it's got the fun bold contrast and stripes!
