Hi there! I just joined, and saw your post, and I'm pretty sure this is what you're looking for. It has a flame pattern on it, but you can just ignore it if you want a more subtle look. Also, if you don't have Acrobat, you need to download a DWF viewer. Not a biggie.http://m-sewing.com/patterns-catalog/men/vests/vest-with-pattern.html
Two others you can use as extra info:http://m-sewing.com/patterns-catalog/men/vests/vest-with-pockets.htmlhttp://m-sewing.com/patterns-catalog/men/vests/vest-with-hood.html
I do a lot of sewing, and another resource for future use is burdastyle.com, but I didn't see the type of vest you want there.
