I used Simplicity #4698, which is now out-of-print, but it is made for a woven fabric. I selected a 4-way stretch, solid black ponte knit from my stash (but of course I purchased it at Fabric Mart last year.) It was a really nice, sturdy ponte knit, so I figured it would be ok to substitute this for a woven fabric.
So here it is! This ponte knit blazer has two side pockets, princess seams and a single button closure. I made size 16 and didn't have to do much altering. The only major alteration I had to do was to bring in about 3/4" at the top of the princess seam. I added topstitching to the princess seams to make it have a more ready-to-wear look.
This blazer has a half-lining, which I wasn't too crazy about at first, but when I saw another blazer at the Tracy Reese store, I decided it was acceptable. I selected a poly faille print to spice up the lining a little bit.
