Since the ad was in grey, it was easy to see all the detail, like where I needed to make darts. I drafted my own pattern out of muslin, and then tried it on 100 times while sewing to get the fit right. I made it out of medium weight jersey from Jo-Ann in a mint green color.
Don't look at the filthy room, please.
Of course I had to screw some things up- obviously, since it was my first time drafting a pattern. The points could have used a stiffer interfacing, since they try to droop sometimes; also, the white zipper.
For future reference, if Jo-Ann doesn't have a zipper that matches, that does not mean buy a hideous white one. I wish I had bought a big metal one, like for a jacket. Then it would look industrial and intentional, rather than home-made.
Also, my old machine does not do zig-zag or stretch stitch, so the hem is falling out as I continue to snap threads.
Overall, I was very proud of myself, and I think it is very flattering.
