If you'll recall,
I attempted this design last month, but it turned into a wadder because of poor fabric choice. And my zipper insertion looked horrible. And the collar was too tall, making me feel somewhat choked. I'm calling that first try an expensive muslin, because this one I'm actually really pleased with. Here's the drawing again to refresh your memory:

Ta da! You might notice right off the bat that my version has no sleeves. I thought them a little strange but edgy at the same time, and couldn't make up my mind if I should include them or not. As it turned out I needn't have concerned myself; there wasn't enough fabric anyway. I barely squeezed out the inside facings, and had to cut the undercollar with lining fabric.

This time I cut 1.25" off the height of the stand collar and now it is the exact height of the shawl collar, totally eliminating the choking feeling. Isn't this fabric so fun? I bought it a year or two ago from Hancock's for a vest I decided not to make. The front side looks like quilted leather and the back is actually fleece. It's thin enough not to add a bunch of bulk but warm because of the fleece. I was concerned the leather-like layer might melt when being ironed or act willy nilly but it was very easy to work with and pressed like a dream.

I added this 1" elastic casing to the back to give it some shape.

I did include the working front pockets, even though they are tiny and I'll probably never put anything in there. The welts were turned on an angle and have vertical and horizontal "quilting lines".

This project stressed me out because of the silly front zipper. On my last attempt, the zipper was wavy and didn't meet exactly at the top or bottom. However, this one went in with relative ease and didn't have any waving issues. I love the contrast of shiny gold metal and matted black leather. I see lots more exposed metal zippers in my future.
Also, I cut each piece out individually so that all the quilting lines matched up horizontally across the front and back.

The second shawl collar is simply stitched on top of the vest and then zigzagged at the edge. I had to do a bit of handstitching where the tip of the collar overlaps the zipper. Here's where you can see the undercollar cut from lining fabric. This was a happy accident as it cuts down on bulk and never shows anyway.

The elastic casing was easily made by stitching the lining and vest fabric together at the top and bottom of the casing. Then I inserted the elastic and closed the ends.

Even though I live in Texas and we have very mild winters, I get cold often. (I must have cold reptile blood or something.) I think this vest will see a lot of use as a warm layering piece.
