The muslin is mildly discouraging. It fits perfectly--except in the bust. I need to adjust for only one cup size, but my first attempt ruined the very slight hourglass shaping and left me with a perfectly boxy, ugly rectangle, not to mention other wrinkles and gaps. Sigh.
Even if I could get the fit right, the muslin calls attention to more important design issues. The biggest problem? The jacket's jewel neckline doesn't do anything for me. I'm going to try making the neckline slightly more of an oval framing the collarbone. Still, I wonder if that's enough. Mary's choice of a v-neckline may be the best way to break up the strong horizontal lines of the fabric.
The other design question: can my short torso handle four welt pockets, or would it be more flattering to have just two?
Taking the time to assess the fit and design at the muslin stage is luxury I may not be able to afford. I may rue the day I mocked Mary's TNT!
