If you'd like to make one like it, I suggest you do as I did, get a fabric vest out of your closet, one that you love how it fits and using the directions below, chart out and knitweave yourself a vest. Keep in mind that its knitweave which means it will not have the give a stockinette piece will have, add enough ease that you can wear something under this (which is why I suggest you measure a woven article rather than a knitted article for your vest measurements).
Zipper was pinned and basted with contrast thread to make sure it hung straight and then hand sewn. After I sewed it I sewed a backstitch seam (by hand) on the woven edge of the zipper rather than sewing it on the sewing machine.
